Can't get the video to run on my phone, so can't form a fair opinion but I think anyone who makes a judgment on a situation like this should at least watch a video of the drill. I have done it in training and it was a real eye opener.

The Tueller Drill assumes a holstered weapon. There were multiple officers here with their guns ready. They could have fired at the first sign of forward movement. I also note that they kept firing after he was on the ground.
