This study examined the relationship between time of exposure to the human face and accurate subsequent photo line-up identification. A volunteer group of 124 undergraduate students was divided into three approximately equal sized subgroups. The three groups were then exposed to a video or a portion of a video depicting a theft. Exposure times ranged from two minutes to 30 seconds. The subjects were then given a questionnaire and shown a photo line-up of the mock perpetrator and five foils. Subjects were asked to identify the perpetrator and mark that identification on the questionnaire. Results of the experiment indicated that the longer a subject was exposed the greater the possibility of an accurate identification.

This research analyzed all juveniles involved in a homicide, both victims and offenders, in the city of Dallas, Texas from the years 1988 through 1997. This study addressed several research questions including the identification of risk factors common to both victims and offenders. Data for this study was obtained from the homicide files of the Dallas Police Department. The findings in part identify specific profiles of the victims and offenders, as well as identifying comparisons of risk factors between the two groups. Also identified are the relationships between the offenders and victims. Conclusions from this research present implications for law enforcement agencies, as well as furthering the etiology of juvenile homicide.

The work of a police officer is stressful and could potentially lead to burnout. As a result, a variety of reactions may occur which include, cynicism, abuse of authority, and in extreme cases suicide. One method which has been proven to be effective in treating officer stress is counseling; however, because of the policing subculture the opportunity to seek counseling has been ignored. In order to successfully manage officer stress, the subculture must be dealt with. Additionally, the officers' family must also be acknowledged as being affected by officer burnout. Counseling services must be made available to the officer's family and through training they can become a source of support instead of an added source of stress to the officer.
