She clearly started the fight, and when you fight you run the risk of getting punched in the face.
This is not the first time this woman has decided to solve her problems with violence.

The first woman was CLEARLY resisting arrest. Usually police will use resisting arrest when someone doesn't jump to their commands - but this woman is in a wrestling match with the officer.

The second woman is an idiot for pushing the officer and I think the officer is justified for punching her. I am glad a taser wasn't used, even though it would have been justified!

The "commentator" is just an idiot!
