First of all, we aren't even talking about the police saying anything out loud. We're talking about them turning their backs on the mayor while at a funeral which, while not verbal speech, is clearly a form of expression that would fall under the 1st amendment. Second, I suspect that a majority of the officers in question were not on the job while attending that funeral.
