Someone please tell me what would be the chances that at a Bush protest we'd see a man packing this kind of heat?

A man toting an assault rifle was among a dozen protesters carrying weapons while demonstrating outside President Barack Obama's speech to veterans on Monday, but no laws were broken. It was the second instance in recent days in which unconcealed weapons have appeared near presidential events.

…Arizona law has nothing in the books regulating assault rifles, and only requires permits for carrying concealed weapons. So despite the man's proximity to the president, there were no charges or arrests to be made. Hill said officers explained the law to some people who were upset about the presence of weapons at the protest.

"I come from another state where 'open carry' is legal, but no one does it, so the police don't really know about it and they harass people, arrest people falsely," the man, who wasn't identified, said in an interview aired by CNN affiliate KNVX. "I think that people need to get out and do it more so that they get kind of conditioned to it."

The article goes on to explain that a site becomes federalized by the Secret Service, so, for instance, the inside venue where the President might be would be off-limits to Mr. Assault Rifle. However, that doesn't help very much if the heat-packer is an unbalanced individual who decides to spray a crowd of, say, health care reform supporters. Nice.
