Without audio, we can't know the whole story. I didn't see any underlying offense. When he tried to take her into custody, she did resist. However, such resistance is not unlawful unless the arrest was lawful.
The one fact that absolutely damns the deputy? The video clearly demonstrates that the deputy lied about some significant details. That, of course, calls into question everything that he wrote in the report.
I can at least say that the officer should receive disciplinary action for lying on the report. Without more information, I can't pass judgment on whether he should be fired or tried as a criminal. Nor can I say whether the woman has a valid lawsuit. The video works for her, though, and against the cop.
