I'm honestly surprised there hasn't been a second shooting at the actual columbine high school. I know it's heavily guarded now with police on basically every corner, but I've seen videos of people walking around in the school's parking lot in the middle of a school day, with kids just sitting out on the steps outside eating lunch. Someone who's 18-21 could easily pass as a high school student, and all they'd have to do is pass as a student for the 15 second walk it'd take to get from their car to the steps where there's like 10 students just sitting around unarmed. They'd definitely be apprehended in less than the amount of time it took them to walk from their cars to the steps, but it still surprises me how not a single columbine obsessed psycho has attempted this yet. I know there have been threats made and whatnot, but how no one's gone through with it genuinely surprises me.
