I think the "justice" op was referring to was about the cop being arrogant and ignorant and being taught a lesson by it. I think people in this thread are getting confused with what video really shows. Most people just see a "bad guy" hitting a "good guy" and automatically will downvote thinking this is an Anti-police video. Let me tell you what I see. I see a poorly trained officer exercising the kind of policing that gets people killed. Let's look at few things.

The distance between the officer and the suspect is laughable. There is barely a foot between them. Show this video to any other police officer you know, a security officer, a soldier, a paramedic in fact anyone who has to deal with unpredictable members of the public and they will tell you it is extremely dangerous what the cops doing. The suspect has obviously not been searched yet, if he had been he would have been cuffed already or would not have his keys still around his neck etc. I make this point to display just how much the officer is showing he has forgotten his training, at that distance it would take less than a second for the suspect to pull a knife out from his pocket and seriously injure if not kill the officer. We know from the video the suspect is much faster and stronger than the cop, and the cop very seriously underestimated the suspect.

The shirt grab. Are you kidding me? I don't think I have seen that hold implemented outside of a fist fight between school students trying to intimidate each other. It's not procedure, its sloppy, its ineffective and worst of all it leaves the cops entire midsection open to a good unguarded stabbing. Arrogance. Pure arrogance about the potential consequences.

The facial expressions. Think about all the other police videos you have seen. What's the one thing most officers seem to have in common? That stone faced blank stare. That isn't because they are emotionless robots, that's because they are taught that something as small as their expressions can escalate a situation. Smirk at some drug dealer getting arrested? He'll mark you the face of his downfall and make you the poster boy for revenge. Laugh at some prostitute in your squad car? Get written up for misconduct. Smile too much at the girl you caught drink driving? Sexual harassment suite. Roll eyes and have a "shut the F up face"? Unnecessarily aggravate suspect. It's not about the suspects feelings, it's about making your job safer and easier. With that in mind go back and look at a officers face. He looks like a dramatic teenage girl trying to convey her stubbornness to the school principal. His face looks like he just wants to be done with it, and while that's a fair way to feel it's very unprofessional to show and lets the suspect know he's getting to you. Also the eyes, at one point he literally rolls his eyes and stares up and at the ceiling for a good few seconds completely breaking his Line of sight with the suspect. Idiocy, that would have gotten him failed had he done it at the Academy.

And lastly the punch. Ever heard the saying "Don't wound what you can't kill?" Well don't get into a fist fight with someone you don't know no matter how righteous you're feeling at the time. That's what their taught, but the officer here snapped, abandoned his training and instead decided to handle it like a street fight and just like could happen in a street fight, he lost. He put himself and his partner in very serious jeopardy. Had the suspects co-workers been hoodlums on street corner and the officer went down like that you can bet the next one to go down would have been his partner followed by the headline tomorrow of two police officers beaten into comas and on life support. This video isn't about "haha the cop got hit. F the police! etc etc" No. It's about what happens when you abandon what you know is the right thing to do and substitute it with your own tough guy attitude, it can backfire, badly. And that is justice. You know who would find this real JusticePorn? All of the officers from his Precinct and any offices that have lost a partner or being injured themselves because of another officers is arrogance.
