Most of our local departments use encrypted radios.
"Over the past few years, an increasing number of municipalities and police departments, including the District’s, have begun encrypting their radioed communications.."[1.]

Does anyone have information about how frequently keys are rotated or exchanged? Seems like keeping 100 radios on the same channel could be hard to do without the potential for human error to leak some data - cops aren't typically very tech savvy.
