I think it was pointed out the shooter did not own the weapons, but his mother did. IOW, he may have been crazy, but he didn’t own a gun either. It’s assumed his mother was not crazy, so what would you do? Disarm her or anybody else related to a crazy person, just to be “safe?”
Read the thread. I can’t help you beyond that.
No, you don’t disarm the mother, but clearly, if her son is shown to have had a long history of violent mentally disturbed tendencies...can we at least place some legal blame on her for not securing her weapons?
Just putting it out there for discussion. Individual responsibility is the key...hers as well as this monster son of hers.
