Ive been im versions of this situation.

It would be disingenuous of me to say Ive stopped someone with a knife attacking another, but as an educator over the last twenty years I've had to stop a number of conflicts both with and without weapons that ranged from pens to bats/pipes. Honestly I've had to do it in scenes that looked way more chaotic than what I saw in that video.

Never once did I think to do my job by harming a student. Now if you place a gun in my hands and I had access to that as part of my job, who knows.

The point im trying to make is I never considered shooting a student to stop him/her from harming another one because my job isn't designed around the power of a gun. That very fact to me highlights one of the major issues with policing in the first place and why I'm pissed off about this whole shit, including the arguments that it had to be an EITHER or choice between the girl in pink and Ma'Kiah Bryant.
