This is a private-run event by a private company and they can do what they want. It's evident when the state trooper shows up he makes sure a riot doesn't start and then gets out of there PRONTO...he knows it's BS.
What they did is wrong EVEN if it's privately run on leased or private land, if for NO other reason than it has the state's name on it...the Alaska State Fair. The company should pay a fine and a settlement and be barred from ever staging another publicly endorsed event. The guy should sue. The state attorney general should look into the whole thing. In fact, Eric Holder should look into it.
If the friggin' black panthers have the right of free speech at a polling place, THIS guy had every right to what he was doing, and our federal government should be on them like white on rice. Investigate and Prosecute, Attorney General Holder!
