I heard a piece earlier today on the radio talking about requiring police to carry personal professional liability insurance for their job as requirement for employment as a way to achieve better accountability by sidestepping the political power of the police unions over the system.

Like marks against a physician or professional vehicle driver, the intent is to basically price the bad cops out of their jobs for lesser infractions before they commit a big one.

Its an idea that I've heard before but never really seen given a whole lot of consideration by the legislatures.
