Yeah, we were there, too. Had just walked in, paid & were looking at the first tables off to the right as you come in...POW!!!
We check ourselves, scan the front for the shooter's location, determine he's not covering anyone else and then see the very guilty, sheepish look on both his and security's faces.
We heard he was pulling a compact Glock out of his back pocket to let security check it, when something he did caused it to discharge, lodging the bullet IN HIS WALLET.
Other info indicated that L.E. was called after he, his wife & baby in the stroller were escorted out the building. He was cited & wifey was said to be 'histerical' mad/upset/angry at him. Bet it sucks to be him right now.
