MAPLEWOOD, Minn. (AP) - Police in a Twin Cities suburb are going to court over the city's body camera policy for officers.

The unions representing 38 officers and eight sergeants in Maplewood say parts of the policy should have been developed through collective bargaining instead of being imposed by the city.

The law approved last spring by the state Legislature requires police departments using the body cameras to adopt written policies governing when the devices should be activated and how the video should be managed.

Reports say the lawsuit filed by Maplewood police objects to random audits of camera footage by supervisors. And they want input on a provision that prohibits officers from reviewing footage before giving a statement following a critical incident that results in severe harm or death.
