Complete the following statement: "After the formation of the modern homeland security environment, the overarching mission of police agencies was to serve in a _____ capacity."

The correct completion of the statement focuses on the role of police agencies within the context of the modern homeland security environment. After the establishment of this environment, police agencies were increasingly seen as essential components of internal security, emphasizing the need to protect the nation from threats that arise from within its borders. This new focus meant that law enforcement was not just about traditional crime-fighting but also about safeguarding citizens from terrorism and other internal threats.

In this context, internal security refers to the protection of the nation from potential security threats that originate domestically, which has become a priority in the post-9/11 era. It recognizes the importance of a proactive approach to law enforcement that includes collaboration with various agencies and sectors to ensure comprehensive security measures are in place. The role of police has thus expanded beyond mere law enforcement activities to include aspects of community safety and emergency response, aligning closely with the overarching mission of homeland security to ensure national safety on multiple fronts.
