Abstract
This study investigated differences in state and local law enforcement agencies participation in homeland security activities within the year after the 9/11 terrorist attacks and 13 years later. Further, this investigation assessed whether there were regional differences for these practices during these same time periods. Activities assessed were based on a homeland security initiatives index. Data suggest that, in the year after the attacks, agencies’ participation in all of Stewart and Morris’ homeland security activities was not high and statistically significant differences existed across several regions for some of these practices. However, since then, the number of agencies participating in all of Stewart and Morris’ homeland security activities increased and statistically significant differences between regions decreased. The increase in participation may be attributed to incentives provided by the federal government. Nevertheless, data suggest that support may be waning within law enforcement agencies to participate in homeland security activities.
