Would somebody please explain the First Amendment to Quentin Tarantino? The film director apparently thinks that freedom of speech is a one-way street: he gets to call cops "murderers," but they don't get to defend themselves.

Appearing on MSNBC show this evening, asked by Chris Hayes if he was surprised by the "vitriol" of police reaction to his speech at a recent rally in New York at which he called police "murderers," Quentin whined: "I was under the impression I was an American and that I had First amendment rights." Poor baby. Yeah, you do. So do the cops. 

QUENTIN TARANTINO: In the case of Eric Garner, in the case of Tamir Rice, I believe that those were murders but they were exonerated. 

CHRIS HAYES: There's something about that word, obviously, which has set off police unions and many police officers. Why do you think? Were you surprised by the, frankly, the vitriol with which they have responded to those comments? 

TARANTINO: Well, yeah! I was surprised. I was under the impression I was an American and that I had First Amendment rights and there was no problem with me going to an anti-police brutality protest and speaking my mind.
