If that 28 year old woman wanted to get back at a school she attended as a child, she sure took a long time to make up her mind about it. And as for killing children who weren't even born when she was a student there . . . that's crazy.
Yeah. Makes one question the narrative that she wanted to punish the school for being mean to her about being "trans." Plus, 20 years ago, none of the other schools were grooming kids to be trans, anyway. It would be interesting to know when she went trans. Probably wasn't on her radar in grade school.
In any case, her other targets were another school, and a shopping mall. Maybe her former school was just enticing because of less security, and because she knew the territory. They said she had drawn maps of her targets, which suggests that was important to her sick, little mind.
Speaking of which . . . doesn't Federal law prohibit purchase of guns by the "mentally defective?" Doesn't gender dysphoria fall into that category? (Plus whatever other problems she was being treated for?)
I believe it's "adjudicated mentally defective," and a lot of crazies haven't been adjudicated. In any case, gender confusion is now considered a resume enhancement; not a defect.
