This whole notion that Grasty violated the 1st Amendment is fallacious in nature.  

The Malheur Occupiers were CRIMINALS.   They had no right to use public facilities in Burns to spread their propaganda to the public, and create more unrest.   If Gasty had allowed these public meetings to happen, he would have aided and abetted the occupation, which everyone knows was a completely illegal act.

There are times when it is in the best interests of the public to censor speech.    Especially when those that want to speak are trying to encourage more people to break the law.
