FWIW, I just watched a video of a body language expert analyzing an interview with the shooter’s brother. Her conclusion was that the shooter was a leftist radicalized by the MSM. It’s a long video but interesting.
At 23:50 he says “Steve said” and then quickly blurs the issue, realizing that he was admitting that he had talked to Steve. She didn’t catch this.
Do mass shooters usually have people that they love? It seems to me that they are usually twisted loaners, even killing those close to them. Steve clearly cared about his mother, and it looks like others too. He was known to have cared about his mother. Men who are evil often seem to have mother issues.
