The terrorist attacks on the World Trade Center and the Pentagon on September 11, 2001, compelled most Americans to imagine the unimaginable. Increased interest was focused on lessons learned, specifically if local law enforcement agencies had made appropriate organizational changes to manage potential terrorism events. The purpose of this study was to assess perceptions of law enforcement officers in the state of Michigan regarding organizational changes post 9/11. A total of 247 law enforcement officers participated in the study by completing three instruments, the Police Unit Assessment of Terrorism (PAT) Scale, Domestic Unit Assessment of Terrorism (DAT) Scale, and a short demographic survey. The officers who perceived their work load had increased since 9/11 were more likely to have more positive perceptions on both the PAT and DAT.
