We called the police and they did nothing.
The police don't get involved in petty squabbles, especially when liberals are at fault. Remember, the police in DC are under the City Council which is very liberal. Walter Reed security is a different matter.
Code Pink has friends in high places among the kook fringe in DC. I wouldn't try too hard to give them an excuse for yanking your ticket.
The fact that CP took exception to the signs is proof they realize that much of their "support" from motorists is actually ill-deserved
