Research has shown that the police industry has entered into an era of homeland security. However, whether the core functions of policing have significantly changed since September 11, 2001, has been the topic of considerable debate. Using secondary data, the research identifies variables that are most influential in predicting whether Texas police chiefs understand their departments’ homeland security roles and responsibilities. The data was originally obtained in 2007 through self-administered surveys of police chiefs attending the Texas Chief Leadership Series (TPCLS) and the New Chief Development Program (NCDP).

The primary goal of this study was to analyze the characteristics of current registered sex offenders in Collin County, Texas, as well as to compare age and gender of the victims of these offenders in order to know who sex offenders primarily target in these crimes. The study also sought to discover geographic patterns of where the registered sex offenders reside for the purpose of keeping communities aware. Participants consisted of 175 registered sex offenders (N = 175) in Collin County, Texas, found on Collin County's and the Texas Department of Public Safety's online public registries. The findings demonstrate that there were significant trends among the sex offenders, their victims, location of residence, and housing complications as a result of progressing sex offender laws. Treatment programs and the reintegration of offenders in the community were also addressed. The meaning of the results in this study can aid in the development of safety and prevention strategies, provide an understanding about the utilization of sex offender registries, and can benefit law enforcement to predict the movement of current sex offenders, along with knowing where to find other potential offenders.
