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.
Looks like the kid was trying to toss his gun, and wasn't too smart about it. Takeaway: if you are holding a gun, prepare to get shot.
Not sure what the kid could have done differently. Maybe keep it in his pocket and keep his hands up and declare it to the officer once tensions have cooled? Hard to say.
You see this in a lot of badge cams, criminals who are carrying grabbing their gun toss it and then getting shot. Either drop it where the officer can see it and don't move, or surrender and then tell the officer as they go to pat you down after you're in cuffs.
It seems like if you want to drop the gun, the safest thing you can do is have your hands up and let go of the gun. That way you have the gun out of your hands and you're still in the position to be arrested.
But then again, the other thing you can do is NOT HOLD A FUCKING GUN IN THE FIRST PLACE AND DON'T COMMIT CRIME but that's starting to become a tired argument.
