So we had a mock school shooting at my High School for training for a whole lot of first responders/emergency/police people.
One of my best friends is in it. I just watched the video. He was sprawled out on the floor covered in fake blood screaming for help while agonizing in pain as he slowly died. It was quite creepy.

I think the good ol' theater group put on a rather convincing display, though.
