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).
