From what I can see, it certainly looks like the cops went overboard on that one. But I also don’t know what took place before that — did he lie down like that before, and then jump up and assault a cop or two before running off again? Maybe he did something like that multiple times. And this was supposedly a three-hour chase (according to the news clip), so lots of stuff happened before this. All of that will play a role in how the officers respond once they reach the suspect.
But just based on that particular clip, yes, the cops were wrong, IMO.
