What model did local law enforcement agencies start integrating into their operational procedures after the September 11 attacks?

After the September 11 attacks, local law enforcement agencies began to adopt the homeland security model as a means of enhancing national security and improving local responses to potential threats. This model emphasizes collaboration among various agencies, increased intelligence sharing, and a proactive approach to potential terrorist threats. The integration of this model into operational procedures was a response to the need for local law enforcement to play a critical role in national security efforts, ensuring that they could better prepare for, respond to, and mitigate the effects of potential terrorist activities.

The homeland security model not only focuses on the coordination of various levels of government but also includes partnerships with private sector entities and the community to create a comprehensive approach to security. This shift marked a significant change in how local police operated, moving from primarily reactive policing to an emphasis on prevention and preparedness in the context of terrorism and other large-scale threats.
