There's some solid posts from both points of view in this thread. The fact he had stabbed someone and wouldn't drop his weapon is certainly a big one. With that said, this post keeps coming to mind:
The more I think about it, the more I feel like the cops could have waited this one out a bit and not had to kill someone.
Which makes me wonder...what if it was a 12 year old kid that just stabbed someone with a butcher knife? Are we still okay with firing 10 rounds into him if he acts like he's going to throw the knife at the cops?If you can’t subdue a legless man without shooting him you shouldn’t be a cop.
