I would lay odds that you are correct. These folks were rude, mis-behaving radical nutjobs IMHO. This kind of activity is not OK in any setting that reflects on this society. That they (same deal, insert as needed) want special treatment and laws to protect the bad behavior.
Lets see how far you or I would get with this if tried....we would have been ejected on our AR$$ES.
If these whacks were subjected to background by the secret service then again...Epic Fail.
