Not in Florida it wouldn't be. Back during the last Presidential campaign a bunch of us were picketing a John Kerry rally and the cops eventually told us we had to be a certain distance from the arena in Orlando. This was after the union goons were seemingly seconds from starting a fight with the likes of little old ladies in our group by the goons.
The premise was that the Kerry group had paid to be there so they in effect "owned" it for that night. The cops were very sympathetic to our side but they said that is the law.
Thanks for the info. I think if some musician leased land from the Gov't, they would be able to restrict video and audio recording as well. So why not the Mormons?
