It would be useful to know...
1. Citizenship status?
2. Arrest/conviction record if any?
3. Were any of his weapons illegally owned, possessed, or carried?
4. Was the property a "gun free zone"?
5. Did he have a social media page? Were there political, antisocial, sick, or threatening statements or links? And, was any of this scrubbed?
6. Was a comprehensive drug screen run, and what are the full results?
Lots more questions, these are just starters.
.
Here’s one more:
7. Party affiliation? It seems a lot of these wackos are registered democrats.
Gun free zones work! Two minute video from MxBest.
