The use of mental health professional consultants to police hostage negotiation teams.

Three hundred law enforcement agencies in the United States that employ a negotiator in hostage incidents responded to a survey regarding the use of mental health professionals as consultants to the negotiation team. Thirty-nine percent of the agencies with a negotiator use a mental health professional consultant to the negotiation team. Police agencies that use a mental health professional as a consultant on negotiation techniques reported more hostage incidents ending by negotiated surrender and fewer hostage incidents ending by tactical team assault and arrest of the perpetrator. Also, police agencies that use a mental health professional as a consultant on the assessment of the perpetrator reported fewer hostage incidents resulting in the serious injury or death of a hostage. Although these results are only correlational, they raise the possibility that the use of mental health professionals as consultants to police hostage negotiation teams may decrease the risk of hostage injury and death.

Murderers' and sexual offenders' experiences of police interviews and their inclination to admit or deny crimes.

This research concerns murderers' and sexual offenders' experiences of Swedish police interviews and their attitudes towards allegations of these serious crimes. The explorative study is based on a questionnaire answered by 83 men convicted of murder or sexual offences. Results show that when police officers interview murderers and sexual offenders, the individuals perceive attitudes that are characterized by either dominance or humanity. Logistic regression shows that police interviews marked by dominance are mainly associated with a higher proportion of denials, whereas an approach marked by humanity is associated with admissions. When suspects feel that they are respected and acknowledged, they probably gain more confidence and mental space, allowing them to admit criminal behaviour.

Psychiatric disposition of patients brought in by crisis intervention team police officers.

BACKGROUND: As part of an effort to improve police interactions with mentally ill citizens, and improve mental health care delivery to subjects in acute distress, the University of Louisville, in conjunction with the Louisville Metro Police, established the crisis intervention team (CIT). CIT is composed of uniformed officers who receive extensive training in crisis intervention and psychiatric issues and who are preferentially called to investigate police calls that may involve a mentally ill individual. METHODS: In an effort to determine the characteristics of the individuals brought to the emergency psychiatric service (EPS) by CIT officers, a comparative (CIT vs. mental inquest warrant [MIW, a citizen-initiated court order to bring someone for psychiatric evaluation because of concerns regarding dangerousness] vs non-CIT/non-MIW), descriptive evaluation was performed. RESULTS: With the exception of a higher rate of schizophrenic subjects brought in by CIT (43.0% vs. 22.1%, non-CIT, P = .002), the demographics, diagnosis, and disposition of CIT-referred subjects were not different in any way from non-CIT patients. Subjects referred on MIWs were more likely to be admitted to a psychiatric hospital than non-MIW patients (71.6% vs. 34.8%, P < .0001), but CIT-referred hospitalization rates were not different from hospitalization rates of self-referred subjects (20.7% vs. 33.3%, ns). CONCLUSIONS: CIT officers appear to do a good job at identifying patients in need of psychiatric care.

"I'd know a false confession if I saw one": a comparative study of college students and police investigators.

College students and police investigators watched or listened to 10 prison inmates confessing to crimes. Half the confessions were true accounts; half were false--concocted for the study. Consistent with much recent research, students were generally more accurate than police, and accuracy rates were higher among those presented with audiotaped than videotaped confessions. In addition, investigators were significantly more confident in their judgments and also prone to judge confessors guilty. To determine if police accuracy would increase if this guilty response bias were neutralized, participants in a second experiment were specifically informed that half the confessions were true and half were false. This manipulation eliminated the investigator response bias, but it did not increase accuracy or lower confidence. These findings are discussed for what they imply about the post-interrogation risks to innocent suspects who confess.

Acute service delivery in a police-mental health program for children exposed to violence and trauma.

The Child Development Community Policing Program represents a national model of community-based collaboration between police and mental health professionals for violence-exposed and traumatized children. Administrative data from clinical records of a 24-hour consultation service were examined through stepwise multivariate logistic regression to identify child and event characteristics associated with a direct, in-person response at the time of police contact. Of 2361 children, 809 (34.3%) received a direct, in-person response. Relative to Caucasian children, Hispanic youth were more likely to receive this form of response (OR = 1.36). An acute clinical response was more likely for incidents of gang involvement (OR = 8.12), accidents (OR = 5.21), felony assaults (OR = 2.97), property crimes (OR = 2.30), family violence (OR = 1.53) and psychiatric crises (OR = 1.29). Acute response was less likely when juvenile conduct problems (OR = 0.61), fires (OR = 0.59), child maltreatment (OR = 0.57), and domestic violence (OR = 0.44) were involved. Incidents that were more severe or involved a primary mental health component were related to utilization of intensive CDCP resources.

Cortisol, learning, memory, and attention in relation to smaller hippocampal volume in police officers with posttraumatic stress disorder.

BACKGROUND: A proposed explanation for memory impairments in posttraumatic stress disorder (PTSD) is stress-induced hippocampal damage due to elevated cortisol levels. We have previously reported smaller hippocampi in police officers with PTSD. In this study, we examined changes in and associations between cortisol, learning, memory, attention, and hippocampal volume in PTSD. METHODS: In a case-matched control study, 12 police officers with PTSD and 12 traumatized police officers without lifetime PTSD were examined with magnetic resonance imaging (for hippocampal volume), salivary cortisol tests, and neurocognitive assessments. RESULTS: Significantly smaller hippocampi and higher early morning salivary cortisol levels were found in PTSD. Subjects with PTSD performed worse on a delayed visual memory recall task at trend level, and made more perseverations and intrusions on a verbal memory task. Negative correlations were found between PTSD symptom severity and immediate recall function, and between re-experiencing symptoms and left hippocampal volume. A positive correlation was found between salivary cortisol level in early morning and right hippocampal volume; however, hippocampal volume did not correlate with memory. CONCLUSIONS: Smaller hippocampi, higher cortisol levels, and memory impairments were associated with PTSD but were not directly correlated to one another. Memory impairments in PTSD do not seem to be a direct consequence of hippocampal size.

Exposure of traffic police to Polycyclic aromatic hydrocarbons in Beijing, China.

Exposure of on-duty traffic police in Beijing to polycyclic aromatic hydrocarbons (PAHs) was investigated during the summer, 2004 using a personal sampling technique in measuring both particulate and gaseous phase PAHs. The results were then compared with those from two control sites away from the street. Exposure levels to gaseous and particulate PAHs for the traffic police were found to be 1525 +/- 759 ngm(-3) and 148 +/- 118 ngm(-3), respectively, representing 2-2.5 times higher levels than those at the control sites. The daily inhalation exposure of the police was estimated to be 277 ngkg(-1)d(-1). Most of the PAHs exposure came from the vapor phase, particularly NAP, FLO and PHE. Based on calculated PAH diagnostic ratios, the major source of PAHs exposure was from vehicle exhaust. The effects of temperature, humidity and atmospheric stability on exposure levels are also discussed.

Training of police officers as first responders with an automated external defibrillator.

UNLABELLED: A short and effective training programme is an essential prerequisite for the use of automated external defibrillators (AED) by EMS providers and first responders. We evaluated a 3-h AED course based on the ERC requirements. METHODS: As part of a study evaluating the effectiveness of AEDs used by first responders (ARREST 4), we trained all police officers in the region of Amsterdam, the Netherlands. By means of a Basic Life Support (BLS) assessment at the beginning of the course and at the end, we evaluated whether BLS can be improved in a 3-h AED course. Through a combined BLS and AED assessment at the end of the course, we evaluated whether AED skills can be acquired sufficiently. BLS skills were measured with the Laerdal SkillMeter in evaluation mode. AED skills were assessed using 13 criteria. By means of logistic regression, we analysed the influence of student characteristics, such as age, gender, previous training, resuscitation experience and motivation for BLS and AED on BLS and AED skills acquisition. RESULTS: Between September 1999 and June 2000, 823 police officers were trained (76% male, mean age 36 (S.D. 9) years). BLS improved significantly (P < 0.001) in all criteria, except for hypoventilation (P < 0.001). After training, 89% of the students were able to use an AED safely and effectively. Self-confidence and motivation improved from 12 and 73% to 99 and 94% over the course (P < 0.001). Independent student characteristics influencing the success of the AED course were: previous BLS training, motivation before the course for an AED, and resuscitation experience that dated back for more than 12 months. CONCLUSION: The majority of police officers can be trained to use an AED safely and effectively within a 3-h AED course. During this course, they also improve on their BLS skills. Successful completion of the course depends in part on the student characteristics.

The crash reduction effectiveness of a network-wide traffic police deployment system.

Random Road Watch (RRW) is a traffic policing program in operation in Queensland, Australia. It differs from conventional traffic policing in that an explicit resource management technique is used which randomly schedules low levels of police enforcement in a manner intended to provide long-term, widespread coverage of a road network and hence maximise road safety benefits. Implementation of the program studied in Queensland covered 55% of total crashes within the state. This study aimed to measure the crash effects of the RRW program in Queensland. A quasi-experimental study design was used for the evaluation incorporating Poisson regression statistical analysis techniques. Analysis of the effects of the Queensland RRW program on crash frequency has shown the program to be effective overall. Estimated program effects were largest on fatal crashes, with an estimated reduction of 31%. Estimated aggregate program crash effects reduced with crash severity and increased with time after program introduction. Crash reductions in the third year after program introduction translated into savings, at state level, of some 12% of the state's crashes of all severities and some 15% of the state's fatal road crashes. Overall, the program produced a significant 11% reduction in total crashes in areas outside of metropolitan Brisbane. The opportunity-cost benefit/cost ratio for the program was estimated to be 55:1.

The dimensionality of trauma: a multidimensional scaling comparison of police officers with and without posttraumatic stress disorder.

This study assesses the multidimensional structure of traumatic events as perceived by police officers and investigates individual differences in the scaling of such perceptions. Forty-two police officers with posttraumatic stress disorder (PTSD) and 40 officers without PTSD were given descriptions of critical incidents they were likely to encounter at work. They sorted these on the basis of similarity and rated them on 15 descriptive scales. The two groups were comparable in terms of relevant background characteristics. PTSD was diagnosed with the Structured Interview (SI-PTSD). The similarity data were subjected to individual differences multidimensional scaling analysis [Carroll and Chang, Psychometrika 35 (1970) 283]. The objective was, first, to identify the basic cognitive dimensions of psychological trauma that police officers use in discriminating between common critical incidents and, second, to test whether officers with and without PTSD apply such dimensions differently when interpreting critical incidents. The same three-dimensional solution was obtained for both groups: (1) emotional reactivity; (2) vulnerability and physical integrity; and (3) moral responsibility. Significant differences were found between the PTSD and non-PTSD groups in the salience of Dimension 2. Results are discussed with reference to other studies that address the meaning and interpretation of traumatic events. Implications for the conceptualization and assessment of trauma and PTSD are outlined.

The use of AEDs by police officers in the City of London. Automated external defibrillators.

The Guidelines 2000 for cardiopulmonary resuscitation recommend shock delivery to victims in ventricular fibrillation within 5 min of call receipt by the Emergency Medical Services. In an effort to achieve this goal, in some parts of the United States, police officers have been trained to use automated external defibrillators (AEDs). We undertook a 3-year pilot evaluation of the use of AEDs by City of London police (CPOL) officers. Over a period of 3 years, 147 CPOL officers were trained in the use of an AED. Four AEDs were placed on rapid response vehicles covering the City of London. An overall call-response interval target was set at 8 min. The CPOL attended 1103 (90%) of the total of 1232 calls to which they were summoned. The mean interval between the first call received and arrival of the CPOL on scene was 8.9+/-4.0 min. The CPOL applied AEDs to 25 victims, 13 of whom were initially in ventricular fibrillation; at least one shock was delivered to all 13. The interval between call reception and delivery of the first shock was 5.5+/-2.5 min. The mean interval between switching on the AED and delivery of the first shock was 24+/-12 s. Two (15%) of these victims survived to hospital discharge. This study has confirmed the feasibility of training police officers in the UK to use AEDs as first responders. The call received to arrival on scene interval should be reduced by improvements in communication between LAS and CPOL.

Seven years' experience with early defibrillation by police and paramedics in an emergency medical services system.

PRIMARY OBJECTIVE: To assess the outcome of patients with out-of-hospital cardiac arrest with ventricular fibrillation as the presenting rhythm in an emergency medical services system utilizing a combined police/paramedic response to provide early defibrillation. MATERIALS AND METHODS: Police and paramedics were dispatched from law enforcement and ambulance communications centers, respectively. First-arriving personnel delivered initial shocks, all using automated external defibrillators. Patients were classified according to response to initial shocks: restoration of pulses with shocks only or in need of advanced life support, including epinephrine. Discharge survival was defined as return to home without disabling neurologic injury. RESULTS: Over the 7-year period of study 131 patients presented with ventricular fibrillation: 58 were first treated by police and 73 by paramedics. Restoration of pulses with shocks only and discharge survival were not different in police and paramedic groups, with overall survival of 40% (53 of 131 patients). Among the survivors, 19% (18/95 patients) obtained a spontaneous circulation only after administration of epinephrine and other ALS interventions. CONCLUSION: Both restoration of a functional circulation, without need for advanced life support interventions, and discharge survival without neurologic disability are very dependent upon the rapidity with which defibrillation is accomplished, regardless of who delivers the shocks. In addition, a smaller but significant number of patients who require ALS interventions, including epinephrine, for restoration of a spontaneous circulation survive to discharge. Short time differences, on the order of 1 min, are significant determinants of both immediate response to shocks and discharge survival.

Prevalence of functional gastrointestinal disorders in women who report domestic violence to the police.

BACKGROUND & AIMS: Retrospective studies found an association between past sexual, physical, or psychological abuse and functional gastrointestinal disorders (FGIDs). However, there are no studies evaluating such an association concurrently with the ongoing abuse. Our aim was to investigate the prevalence of the main FGIDs, functional dyspepsia and irritable bowel syndrome, in 70 women reporting a situation of domestic violence to the police and to evaluate the level of psychological distress and its relationship with the presence of FGID. METHODS: Through an interview between a social worker and the woman reporting abuse, digestive symptoms, psychological status, and type of abuse were recorded. These data were matched against police records. Functional dyspepsia and irritable bowel syndrome were diagnosed according to Rome II criteria. RESULTS: Seventy-one percent of the women had an FGID: 67% functional dyspepsia, 47% irritable bowel syndrome, and 43% both. In two thirds of the cases, FGID onset occurred simultaneously with or soon after abuse onset. Only 34% of the women had sought medical attention for FGID symptoms. No differences were found between women with or without FGID regarding age and type or duration of abuse; psychological distress tended to be more severe in the group of women with FGIDs. CONCLUSIONS: Most women who suffer domestic violence (reported to the police) have functional dyspepsia and/or irritable bowel syndrome and also have elevated psychological distress. This has important implications, not only for comprehensive health care of women in a situation of abuse, but also for medical treatment of women with FGIDs.

Police responses to sexual assault complaints: the role of perpetrator/complainant intoxication.

This study explored the impact of victim and perpetrator alcohol consumption on police officers' evaluations of an alleged sexual assault and their reported likelihood of charging the perpetrator. Two hundred and twelve police officers were presented with a vignette depicting an acquaintance rape in which the beverage consumption (beer, cola) of both the victim and perpetrator was systematically varied. Results indicated that the officers' perceptions of the complainant's intoxication level, as well as the gender of the officer, influenced officers' evaluations of the alleged sexual assault. The more intoxicated the complainant was perceived to be, the more negatively she was viewed. Female police officers evaluated the victim more favorably than male officers. The only factors related to the officers' likelihood of charging the perpetrator, however, involved their assessment of the complainant's credibility and their perception of the likelihood that the perpetrator would be found guilty in a court of law.

The injury pattern of a new law enforcement weapon: the police bean bag.

STUDY OBJECTIVE: This case series describes the injury pattern of the police bean bag, a new weapon adopted by US law enforcement agencies. METHODS: Retrospective chart review between 1996 and 2000 identified bean bag injuries. Autopsy data were gathered for 1 fatality. Circumstances of the shootings, toxicology results, and psychiatric diagnoses, if any, were recorded. RESULTS: Thirty-nine men and 1 woman between the ages of 16 and 77 years were shot by officers of either the Los Angeles Police Department or the Los Angeles Sheriff's Department. The fatality was caused by massive hemothorax after thoracic penetration. The locations of serious penetrating injuries included the thoracic cavity, eye, abdomen, arm, and leg. Blunt injuries included splenic rupture, pneumothorax, compartment syndrome, testicular fracture, subcapsular liver hematoma, and cardiac contusion. Complications included hemothorax, pneumopericardium, wound infection, compartment syndrome, and osteomyelitis. Psychiatric consultation was requested for 27 (69.2%) of 39 surviving patients. The Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) Axis I was used for diagnosis in all 27 patients. Psychosis was diagnosed in 16 (59.3%), suicidal ideation in 15 (55.6%), and major depression in 6 (22.2%) of the 27 cases. Schizophrenia had previously been diagnosed in 7 (25.9%) of the 27 cases. All but 1 of the patients had toxicology screenings performed, and the results of 29 (74.4%) of 39 were positive. Of these 29 positive results, 15 (51.7%) were positive for alcohol and 8 (27.6%) were positive for cocaine. CONCLUSION: Awareness of the broad scope of potential injuries mandates a thorough evaluation of both blunt and penetrating trauma in patients shot with police bean bags. The scope of these injuries raises significant public health considerations because use of this weapon has been adopted by law enforcement agencies in all 50 states and at least 10 countries.

Microwave emissions from police radar.

This study evaluated police officers' exposures to microwaves emitted by traffic radar units. Exposure measurements were taken at approximated ocular and testicular levels of officers seated in patrol vehicles. Comparisons were made of the radar manufacturers' published maximum power density specifications and actual measured power densities taken at the antenna faces of those units. Four speed-enforcement agencies and one transportation research institute provided 54 radar units for evaluation; 17 different models, encompassing 4 frequency bands and 3 antenna configurations, were included. Four of the 986 measurements taken exceeded the 5 mW/cm2 limit accepted by the International Radiation Protection Association and the National Council on Radiation Protection and Measurement, though none exceeded the American Conference of Governmental Industrial Hygienists, American National Standards Institute, Institute of Electrical and Electronic Engineers, or Occupational Safety and Health Administration standard of 10 mW/cm2. The four high measurements were maximum power density readings taken directly in front of the radar. Of the 812 measurements taken at the officers' seated ocular and testicular positions, none exceeded 0.04 mW/cm2; the highest of these (0.034 mW/cm2) was less than 1% of the most conservative current safety standards. High exposures in the limited region directly in front of the radar aperture are easily avoided with proper training. Results of this study indicate that police officer exposure to microwave radiation is apparently minimal. However, because of uncertainty in the medical and scientific communities concerning nonionizing radiation, it is recommended that law enforcement agencies implement a policy of prudent avoidance, including purchasing units with the lowest published maximum power densities, purchasing dash/rear deck-mounted units with antennae mounted outside the patrol vehicle, and training police officers to use the "stand-by" mode when not actually using radar.

Policing, collective action and social movement theory: the case of the Northern Ireland civil rights campaign.

In this paper we examine the relationship between social movements and the police through an analysis of the Civil Rights Movement (CRM) which emerged in the late 1960s in Northern Ireland. Following della Porta (1995) and Melucci (1996) we argue that the way in which episodes of collective action are policed can affect profoundly both levels of mobilization and the orientation of social movements. We also submit that the symbolic and representational dimensions of policing can be a significant trigger in the stimulation of identification processes and collective action. The paper concludes by questioning some of the assumptions contained within social movement theory, and their applicability to divided societies such as Northern Ireland.

Coping strategies among police recruits in a high-stress training environment.

The use and impact of coping strategies were explored in a setting of environmental stress. The sample consisted of 180 police recruits subjected to training stress in a U.S. police academy. Measures of coping, personal distress, and life stressors were used. Recruits who scored high on personal distress tended to use more coping strategies than those who had lower distress scores. These findings suggest that the magnitude of personal distress may be an important factor in determining which array of coping techniques is used. In terms of effectiveness, the coping strategies of distancing and planful problem solving significantly reduced distress. Escape/avoidance and self-control coping did not appear to work in the police situation and significantly increased distress.
