And of course, the recent shooting by a retired captain - who put together the local SWAT team back in the day - who shot a man and his wife for texting their 3yo daughter in a movie theater. I hate texting in theaters (I do rarely go, though), but still, a capital offense.
They get away with it because there are no repercussions for them. Witness the jackass in Ohio who threatened a guy with immediate summary execution for carrying concealed. He's trying to get back on the PD, claims he was wrongfully fired for PTSD.
The retired PD captain is under arrest, but not for murder.
