When the police are called to the scene of a physical altercation it's hard to complain when they arrest everyone and then let the parties weigh the evidence later.
He was in jail for over 48 hours before being release. There's no excuse for that.
Where did you see that he was in jail for 48 hours? I don’t think that’s the case.
He was arrested at 5am Saturday morning. The case was dismissed Monday morning. So it was 48 hours. However, he didn’t get locked up for slapping the girl. He got locked up for the ensuing fight with the guy, who sustained injuries from the fight. So it was a good arrest at the time. Only when they could go over all the evidence did they say self-defense.
