Idiot cop thinks flipping him off, which has been upheld as free and protected speech, is both disorderly conduct and obstruction.
Another cop committing blatant federal crimes. Not only is flipping off police protected free speech, but it's also been upheld by the Supreme Court that free speech can not be interference/obstruction.
Now the real question is, why aren't lawless cops being held accountable? It's not law and order they want, it's dominance.
