> having a conviction for domestic assault; > having a drug or alcohol addiction; > having a TBI 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.
