I watched the last bit in slow motion a couple times. When the guy starts his charge at the cop, he is on the far side of the sidewalk. In two seconds he gets across the sidewalk and runs nearly to the end of a parking stall. How far is that, 30 feet? And he was a fairly big guy; he didn't look particularly fast.
It made me think about attacks that come with little or no advance warning. If that bad guy had been going after me, without warning. I can only hope that I would have perceived the threat and at least hand my hand on my gun by the time the guy got to me. I'd likely be dependent on my one-hand grappling skills against the knife for a second, maybe longer, depending on how I was doing. I like to practice shooting, but I never practice grappling. I think I should change that.
Life (death?) comes at you pretty fast.
Here ya go... ground grappling sucks.
