A very common factor in such mass murders is the use of antidepressants. Having seen up close what happens when someone on such medication misses a few doses (extreme & systematic rage), I'm stunned that there has not been intense investigation into the correlation.

People always mention mental illness, but other things are more common: being male; having a conviction for domestic assault; having a drug or alcohol addiction; having a TBI.

Other countries prescribe anti-depressant medication in similar quantities to the US, and those countries don't have the same problems of violence that the US does.

I know the YouTube incident, specifically, was not a mass-shooting incident (4+ casualties, not including the shooter) but the comment you replied to specifically mentioned mass-shooting.

That males are overrepresented seems fairly self-evident, but is there a noted link between DV, TBI, and addiction(s) with mass-shootings? I've never heard that angle.
