Probably this, less altruism and more "this nigga, who we all hate, just attacked dat pig- now we can fuck 'im up!" Chances are, some of the blacks in the mob were the ones who called the cops to the scene to deal with this particularly niggerish nigger. So they all stayed out of the cop's way when he showed up and started to try to deal with him, but the nigger overpowered the **fat, out-of-shape cop who really needs to take some jiu-jitsu classes and learn how to wrestle;** this left the niggers with a dilemma. Either the nigger kills the cop and brings down the wrath of the police department on the lot of them, *or* they can step in and *legally* lynch the fucker. Again, I doubt there was this much thought put into it in the moment. They saw the cop as the solution to their problem, which was this nigger- that solution was being destroyed by that problem, so they finally attacked the problem themselves in a way that they understand (violently). This officer should be humiliated for his performance here. That skinny nigger should be as easy to handle as a wet noodle, but you can see the cop panic as soon as he hits the ground. This is why Jiu-Jitsu is important for cops, they end up scrambling on the ground with suspects very often- knowing how to retain their weapons and control a spastic nigger should be a requirement. Also no more than 15% body fat.
