There were reportedly two people carrying AR-15 assault rifles. These are only semi-automatic weapons, but one has to admit the Secret Service might in fact feel under-gunned compared to them.
It should be noted that this is perfectly legal in Arizona, but the man apparently told reporters that he was carrying the AR-15, "Because I can do it. In Arizona, I still have some freedoms."
The point is that just because you can do something doesn't mean you should. You can drink yourself into a coma, but should you? This is a Presidential event, by the way, but other events without Obama attending have been marred with similar gun-carrying attendees.
This isn't about gun rights. Obviously they have their rights. However, can anyone remember this happening at anytime in history before? Why is this happening now? It makes one fear for our President's life.
