“2) Often we know someone is guilty”
Funny, I thought we lived in a country where the presumption of innocence trumps what a cop “knows.” Cops can’t be judges., This guy may think he’s “protecting” the citizens of Long Beach, but he’s breaking the law! Your friend’s son should probably find another line of work.
PS I have a good friend who was LAPD in San Pedro (for ten years). He quit because of these kinds of illegal tactics, and was unwilling to abuse people because what the cops “thought.”
By your logic, OJ did not commit murder then.
