I don't want to discourage lawlessness or violence...but I would like to note that anybody who punched one of these punks outside a funeral would be bulletproof as far as being convicted by any jury. In fact, I don't think these pukes have a First amendment right to do this kind of protest at a funeral, because it falls under the fighting words exception.
Ant decent cop wpuld look the other way I'm sure.I'm not one for violence but hey , lets be real . One good old fashioned beating would give this nut something to think about the next time he plans a sick event like this . Smak him around and tell him these more on the way if he does it again .It's worked well MANY times in the past in other situations.
