We don't even know if he has parents. We don't know who lives with him. But I'm not going to judge the parents, we don't know them. It's not that hard to hide things from parents, especially if we're looking at a single parent, or even both parents, working long hours outside of the home. We know about parents working 2 jobs to make sure there's food on the table. This kid was quiet, didn't cause any trouble, was on the Principal's Honor List one year, was in the football team. So, he was quiet but not quiet enough for people to find it weird. Some parents choose to ignore the warning signs, but others just don't see it. If I had a child that never gave me any problems, that behaved both at home and at school, had okay grades, was even part of a sports team (meaning, he wasn't really isolating himself) and I never heard that child talking about guns and I never saw any violent behaviour, I don't think I would be thinking "oh no, my kid is probably going to end up shooting up the whole school". Not everything is black and white. The "born to kill" shirt is very alarming though but yet again, maybe that was posted on a secret account, maybe the parents didn't have social media. I'm not defending anyone, this is terrible and nothing - I repeat, NOTHING - justifies this hideous massacre, but I also don't think we should start throwing stones at the parents already, it doesn't do any good and we just don't know enough yet. Maybe they did know and didn't care, or maybe they were clueless. It has to be really hard to have your own child do something like this.
