Police Activity has a video showing not just the shooting, but the lead up and aftermath.
It shows the desperate struggle of 6-8 officers rendering aid trying to save his life, and the near breakdown of the officer who shot him.
But its flagged to all hell and you're not even allowed to use the share function.
Here is the video: https://www.youtube.com/watch?v=97uYOrxYu6k
Heartbreaking that the police officer was forced to endure this.

There is also complete videos here, the more gruesome elements was edited out by Police Activity.
The kid was unlucky, I think the cop must have hit a major artery because it looks like he's dead almost immediately after hitting the ground.
He was very unlucky. In my opinion his goal was to hide the gun and then comply with officers. He was just a dumb 13yr old who was in WAY over his head, and unfortunately died as a result. The cop had every reason to believe he was about to be fired on, and exercised the only option you have in that scenario.
