Re: Police in court?
Put you tin-foil hat away; it's not unheard of for police officers t be prosecuted, and convicted of crimes, as well you'd know if you'd even bothered to do a cursory search on google.
It's also not that common (given the total number of officers), and understandably so, since most police staff are well behaved individuals, and have to undergo rigorous pre-employment checks in an effort to try to make sure that this is the case.
