Since when is it illegal to flip off a cop?

Frank Patti of Long Island crashed his chopper after flipping off two cops who then gave chase.

The story says he charged with fleeing police, resisting arrest and several traffic violations. It also says that police don’t know if he has an attorney.

Rather, the cops should be charged with excessive use of force, reckless pursuit or anything else that will stick.

Last I checked, we had a First Amendment.
