It's all due to mental illness the gun folks say. Don't blame the guns. Blame the crazies who get access to them. But we don't want to prevent them from access to guns. Trump signed a bill that ALLOWS mentally ill people to purchase guns. So he enabled crazies. He wanted to make things easier for them to carry loaded weapons so when they were were in their bat-sh** crazy moods they something they could use to get attention. Isn't he swell?
