Cook County Jail Guard Charged With Punching Inmate, Knocking Him Down.
40-year-old Rico Palomino, a 12 year veteran corrections officer at the
Cook County Jail in Illinois, claimed in his incident report an inmate
"turned around abruptly" and grabbed his shirt, for which he had no
choice but to act in self defense by striking the inmate with his open
palm to "create a safe distance between himself and the detainee,"
reports NBC Chicago. The trouble is, the incident was caught on tape,
and rather than show the officer was responding to being grabbed
suddenly, it shows the cop casually walking up to an inmate and suddenly
sucker punching him viciously in the face leaving him bleeding
profusely from the mouth.
