Study Simulation of Run, Hide, Fight at Columbine

Someone sent me this and I thought it was pretty interesting. It's a research project to test how the current active shooter mitigation policies (Run, Hide, Fight) may have been utilized during the attack on Columbine.

I'd recommend watching the whole thing, but if you are only interested in the simulations, the times are (roughly) 4:40 and 10:07. I think there are mistakes, as I don't believe they got the order of the victims right. For example, I think they have Kyle being killed last instead of first. But, it's interesting nonetheless.
