Rather than assuming guilt on anyone's part, let the system play out.
Getting arrested is in no way proof of guilt or fault. There is this little thing called a courtroom. Cops have to make arrests based on what the law says they must do, and based on stories told by participants and witnesses. Sometimes there's a lot of lying that happens, but cops aren't lawyers or judges and can't always figure out the truth on the scene.
I was on a jury where a young women with bruises and scrapes on her knees got this guy arrested for battery. As it turned out, the girl got angry, and inside the guys truck started kicking the crap out it, breaking the inside mirror, tearing off the glovebox door, etc. He stopped the vehicle, got out, opened the passenger door and told her to get out. She wouldn't. She just kept destroying the inside of his vehicle. He grabbed her by the arm, and put her out. Then got in and left the scene.
She calls the cops and he gets arrested. Why? She lied and she had bruised knees. Even with two moms on the jury, no one had second thoughts. The girl was the aggressor and the guy acted in a reasonable and restrained way. That she got bruised knees from going to the ground by him grabbing her arm and pulling her out of the truck she was destroying was just too dang bad.
Who knows what happened in this case. I don't care if you are a 280 lb. football player; an irate woman can be the aggressor and wind up getting the bad end of the deal for sure. But that doesn't make the guy guilty or a bad guy. A bruise isn't a life threatening injury nor is it proof of vicious action on the part of the guy she's accusing.
But, it also could turn out that he is a woman beater and he ought to be jailed.
