The purpose of a neighborhood security patrol program is to guarantee a greater sense of safety and security by employing private security patrols to assist and supplement the services performed by the local law enforcement agencies. The security patrols may be armed under Section 15 of this Act. The security patrols shall not have the powers of arrest, but shall act within allowable legal limits (including the power to detain for police arrest). The security patrols shall be completely liable for their actions, indemnifying the municipality and county, the sponsoring organization, and all participants. The security patrols shall be available to the entire community through a dispatch telephone number and shall be directly accountable to the community through its governing commission. The governing commission shall establish guidelines, such as the hours of service, the areas of focus, and the procedures for bidding for the patrols.
