What is the test for making obscene gestures toward a police officer and yelling profanities in Spanish?

What then is left? Defendant relies heavily on the fact that Duran was making obscene gestures toward him and yelling profanities in Spanish while traveling along a rural Arizona highway. We cannot, of course, condone Duran's conduct; it was boorish, crass and, initially at least, unjustified. Our hard-working law enforcement officers surely deserve better treatment from members of the public. But disgraceful as Duran's behavior may have been, it was not illegal; criticism of the police is not a crime. Houston v. Hill, 482 U.S. 451, 461-63, 107 S.Ct. 2502, 2509-10, 96 L.Ed.2d 398 (1987).
