It's awesome that this guy did in the problem he is a true hero. Not taking anything away from the man at all total respect. I doubt he was thinking oh yeah John Burns taught me how to do this or that. Or even the fact of what could happen and what was going on. He knew there was a school shooter and a problem and his kid was in that school and he was going to do all he could. He never weighed in about being a hero before he done it or nothing. And probably to this day does not consider himself a hero. He did what he had to do
