here's some fun stuff
the mollen commission from the nineties, this was after the knapp commission from the seventies
"Today's corruption is characterized by brutality, theft, abuse of authority, and active police criminality"
how much worse is it today? are these the types of licensed & screened people they talk about who should be carrying guns?
