That is not what the DA said.The DA's office just said that the guy was not in the house when this took place. That is a pretty strong defense.
As a father of two girls I can understand how this makes people's blood boil. It certainly does mine (and my daughters were both over 18 when they started College but I still would have taken a baseball bat and smashed something if...). But that aside, a 21 year old College Senior having sex with a 17 year old girl at a party should not be a reason for not employing him.
More so there being a report that the guy was not there.
Before making assumptions about others and this case, I'd suggest you read that article more carefully and perhaps some others to educate yourself on the case.
I'm not saying Araiza is definitely guilty of gang rape but if I'm in an NFL GM, I'm staying away.
