This guy was being dumb, rights aside. Just because something is legal doesn't mean it's acceptable or a good idea in any way.

IMO, the way to deal with this guy would be to detain him until after the rally, then release him with no charges. I'm all for the second amendment, but I think there are some situations where common sense trumps an individual's rights... this being one of them. They had no way of knowing whether this guy was just making a statement or whether he actually intended to harm Obama. If it turned out to be the latter, the second amendment would be at a much greater risk of getting dismantled.

Like I said before, I agree with him in principal, but not in execution.
