other than the fed shit, which I agree is suspicious, are any of those things really surprising? I'd see them more as symptoms of the root cause (someone profoundly unhappy with life) than the cause of the shooting.

Not saying feds don't do mass shootings gayops, las vegas was obviously the feds murdering people and pinning it on a random dude and the black grocery store shooting waa obviously fed grooming, but SSRIs are a depressingly common medication and focusing on them and supernatural explanations distracts from the real problem which is that we have an entire generation of profoundly unhappy and hurting people and a government who is so evil it refuses to solve the problems that create such people and instead grooms them to hurt others.
