While some will argue and debate the relative effects of different guns and ammo, it may be important to remember that 5 innocent people are dead. One more is clinging to life. I would like to know how and when this dirtbag bought his guns. He had been arrested several times, never convicted so as far as I can see he had every right to purchase as many guns as he wanted. Everyone can agree how important it is to keep guns out of the hands of convicted felons, what do we do with mentally unstable people with no convictions on their records? Or people that have no outward signs of mental illness and no convictions? This is the trick box we have put ourselves in and I will have much more respect for the 2nd Amendment folks if they can address these issues.
