You all know, back in the day when men used straights (har har) in the city I lived in Cops walked a beat. No cars then and the guy knew everyone in the neighborhood and if you didn't belong there he knew it and in those days cops were big guys and either you moved along or you got a crack behind the knees with his nightstick. No such thing as police brutality then. The general perception was if you got it you deserved it.
I guess things have changed.
