This is an opinion piece about something in the news involving politics.
Plus, this doesn't portray police in a particularly positive light. In it he says basically: 'Don't want to get shot? Do what I say when I say it, because I have the power to kill you and you don't know if I've been having a bad day today or not.' That's is totally absurd; so I don't think flagging it is denying cops freedom of speech.
