Every cop in this video could be a hero tonight. Just write a little note and then do what needs to be done. Be a hero for once. You should really do it this time. If you're a cop and reading this, I believe in you. Do it. It's your one opportunity at redemption.

Not only did cops with long guns have their tasers out, ready to stop parents from saving their own children, it looks like the cops have one parent pinned to the ground.

You can hear one person yell, "what the fuck are you doing to him? Let him up!"

At least one additional kid died directly because the cops were incompetent.

"When the cops came, the cop said: 'Yell if you need help!' And one of the persons in my class said 'help.' The [shooter] overheard and he came in and shot her," the boy said.

One thing I heard in this video only after several viewings was a cop saying "we're taking care of it" and a parent yell back "bullshit, he ain't dead yet!" It makes me wonder how they knew from the parking lot. The Washington Post reports gunfire could still be heard at 12:52 pm
