Facepalm to the infinite. this isn't about the arrested girl (no context to know if he is right). and no one is not saying he should "back off", he simply can't distribute punches to those who didn't punch him (or any other kind of damage)

about the bolded part: had he done that, he would go to jail for a huge amount of time.

Trained woman vs a trained man?   For your point to be valid a trained woman would have to be able to lose to an untrained, out of shape man who is smaller.

To say you can never hit a woman but it's fine to hit a man, you have to prove that every woman is inferior to every man physically.

It's really simple. if he didn't had the right to arrest the other woman, then the woman in pink has the right to help. but regardless of that, she just made sure to remove his grip from the other woman and keep a distance between them. she didn't threaten his physical integrity but he punched her directly in the face for no reason. there's no way around it, HE MUST GO UNDER ARREST, period.

what part of NOT PUNCHING OTHERS FOR FREE he didn't understand?

I am not saying womankind is inferior to men. I've seen a woman get hit by a man in a fight and I have not thought the same since  (he wasnt much larger than her either). From life experience I've realized we both have our strengths and many opportunities should be equal. Let me ask you question is a male cop sexist if a female cop gets beaten up and he feels to need to come to her aid? 

However, do not manipulate this. You spoke of equality so I created an equality in the sense of a fight. As fair match with equal bodyweight and equal height. Rhonda Rousey vs Urijah faber. Technically two of the best in their respective divisions. 

First, your punctuation and grammar are absolutely atrocious. 

Second, and more importantly, you are 100% wrong. That cop had every righ to punch that woman in the face. He also had every right to place the first woman under arrest. They jay-walked. He decided to enforce the law. They decided to ignore him and try to brush past him. In what universe do you think that's how society should work? What exactly was the officer supposed to do? Follow behind them begging them very nicely to please stop so that he could do his job? 

Don't be such a dunce.

If that's how the world worked how would any law be enforced? How could any police officer actually do his job if people that broke the rules were just allowed to walk away from him without him being able to retsrain the person?

In fact, that woman who tried to free her friend by putting her hands on the officer should have gotten more than a single punch to the face. Police officers carry guns, batons, and pepper spray on them at all times. You can't have disorderly civilians grabbing at them. I'm sure the women in pink didn't indend to grab his gun and use it, but can the cop actually take that chance? His safety is the priority in that situation. The safety of the woman who could potentially take one of his weapons and use it against him is an after thought.

Sure he can.  I mean, you can't just physically obstruct the police from making a valid arrest.   If you get physical with a cop they are well within their rights to subdue you physically to make the arrest.

Otherwise everytime there was a robbery they'd just pay a bunch of people to gently hold back the police by not striking at them but making it so they couldn't get past them without physically stopping them.

that's the entire point, she didn't get "physical" with him. she was no physical threat (she didn't hurt him nor showed any weapon) and there was a small distance between them. he was free to pepper spray her out of the way but instead he closed the distance and delivered a punch = free agression = jail for him
