I wasn't aware that you have looked through his medical records, previous criminal records, or had conducted psychological evaluations of this individual up until this attack. As of right now, schizophrenics who watch ISIS videos all day, and have not committed a felony have the RIGHT to walk into a store and purchase a semi-automatic rifle with no background check, mental evaluation, exam, or any law enforcement knowledge of said purchase. The only time anyone knows this individual owns this gun is if it turns up stolen, or they've used it in a crime. That to me is absolutely irresponsible!
