same thing happened in a bar to me 11 years ago... except I was alone, and decided to step in and stop the dude from beating her silly... my mistake cause she jumped on my back and started wailing on me as I was slammin the dude across a series of tables... of course the cops show up and haul them both off to jail, I was freinds with the bar owner and everyone at the place said I just broke it up... so no bad shit happened to me... guy left with a broken arm and missing teeth, she was just battered and blue...looking back on it I should have just let him knock her out then kicked his ass...
