Well, we should be thankful that the evil assault rifle wasn't able to overwhelm this poor man's sense of conscience. That's really the only thing that stopped him - his triumph of will over the unholy influence of such a horrid weapon that was urging him to commit mass murder.
Or so the anti-gunners argue.
In the minds of those who would use this near miss as any kind of example of why waiting periods (or bans, or terms like "assault rifle" applied to rifles not meant for assault) will stop people, they want you to believe that the hardware is the catalyst. In this instance, clearly, it was not the hardware. He was denied in October, and had been stewing over it (in some way) since then. Folks, the Super Bowl is in February. After a quick calculation you can see that he waited a full three months, and possibly a bit more, before he set his plan in motion by purchasing a gun to carry out the murder.
And you know what, sometimes that's going to happen. Laws or not. Folks have snapped before, and they'll do so again. When and who is impossible to say in a free society, and for all the heartache that follows a case where violence is visited on the innocent, I'd rather live in that kind of society than one where we're all vetted from day one, watched, prodded and shackled until we die.
