lol this was a good 20 min in and out reading. i dont have much opinion about guns and the crew here, but i would think that the detaining of a person with an open gun would to protect the safety of others. sure this guy went to many places with his gun, it is perfectly legal to carry the gun in the fashion he did, but what if some crazy guy at this assembly of people got a hold of his gun, then what? that should be the only real reason they moved this guy from the rest.
so what if the guy with the gun was walking down the street and that scenario happened ... you could place a ton of what if's on any situation but what if's aren't grounds for trumping laws, especially when someone is following the laws
not to mention ... someone who is crazy enough to attempt to kill a presidential candidate is not going to take the chance he finds a gun at the event ... he's going to come prepared
