@coldjoint,
Go back and read some okf the accounts of Cruz's behavior. He'd been oout of control, violent, and aggressive since middle school. He'd terrorized his neighboras and their pets, his family, and his mother--she was thinking of giving up her parental rights in him. He'd been reported to the cops something like thirty times, been expelled from school for his behavior, been in therapy and dropped out. Basically it sounds like he'd been thoroughly unpleasant and dangerous to be around for years.He bullied everybody else, which led to being bullied back. He was sick, and sa lot of people should hsve red flagged him. Appoarently a number of people did, but he still bought guns legally and killed 17 people,at random, for which there is NO excuse.
