From what I've read and heard thru radio and Dooleys press conference he wasn't throwing at cars, they were trying to hit a garbage can from the balcony and some missed and hit a parked car. It started with a golf ball like a basketball shot you see on tv but went to emptys.
The other car was damaged the following day while Bray was on Campus and thus no charges. It was silly but nothing different than most of us have done. Being a starting qb or regular student has nothing to do with it.
Ye without sin, cast the first golf ball
