It's not an ex wife as reported last night. It's a woman who was living with him. He kicked her out and smacked her around when she came back to get her stuff. Witness reports he even said at time of arrest "She hit me first!" LOL.... LAPD report says her face was battered, hence the felony battery charge vs misdemeanor battery charge.
The real reason- it said in the article that the wife's lawyer denied it. He thought he was being so clever because no one else would notice it. This wasn't liberal thing- this was no thinking. The woman was not the estranged wife.
