The shooter is reported to have had multiple guns and a large supply of ammo. Thankfully, the security guard stopped him by wrestling the shooter to the ground (after taking a bullet), before he was able to commit mass murder. He also may have been carrying a Chick-fil-A bag. Both Chick-fil-A and FRC support traditional marriage. Gaystapo?
