For the life of me I couldn't count how many shots were fired, what with there being 3 guns trained on him, but I'm fairly certain there were at least 10-15. At that range, a lot of those had to have hit their mark. Then one of the cops says after "He's got blood on him." Really? Ya don't say? Not sure how that's supposed to prove that he stabbed anybody. I mean, yeah if you stabbed someone, you're probably going to have blood on you. But last I checked, having 3 people that supposedly train in the accurate use of a firearm do a mag dump on you will probably produce some blood, too.
I want to say the video quality is too poor to draw any kind of armchair lawyer conclusions, but I'm having a hard time even conceding that, given what you can see. But, since I don't know the whole story, I'm still not comfortable letting myself form an opinion one way or the other. Either way, though, he did look compliant, and it'd be nice to have seen him get his due process.
