Gun store owner who sold this asshole guns said he "never gave any indication or reason to believe he was unstable. All necessary background checks and procedures were followed."
What's the gun store owner supposed to do? I haven't looked into what the guys background was, but if it was clear, you would have sold him the weapons to had you owned the store. Unless you employ a gunslingin' clairvoyant, it's gonna be difficult to tell what someone's future intentions are.
I think it's silly to assume someone who is mentally stable with a gun will remain mentally stable with a gun. Power corrupts and the power to kill can definitely corrupt.
I agree. I'd bet nearly 100% of murders/mass shootings that are carried out with legally purchased weapons are done by people who passed the initial background check. It's well past time we tighten that process. I just don't know how it would be done. Mandatory psych evaluation and what would be the equivalent of a concealed carry class could be a good start. It would make folks have to wait at least a month, minimum, before they were eligible to purchase a weapon. Maybe the psych evaluation is a yearly/semi yearly requirement to maintain the license?
