It's hard not to use an eye-test when sizing up a situation, but it's a dangerous game to play. You could be on the wrong end of the next Ronda Rousey. In the end, everyone knows that if you strike an officer, bad stuff is gonna happen. I've been really really drunk and have never even considered such an act.
I bounce back and forth on these scenarios. A drunk person, regardless of gender, doesn't deserved the retaliation that was received. It was clearly excessive. On the other hand, the police officer shouldn't have to be a punching bag waiting to see if the offender is going to escalate their violence.
I agree with others saying that she should have been escorted out in an entirely different manner. That's where the real problem originates. Clear out the people between the offender and the POs and then cuff her and walk her out. Taking a drunk person off her feet and then carrying her off like they were moving a couch was really stupid.
