Dipshit at Sandy Hook did well enough.
THough I do agree gun haters should be forced to deal with that which they seek to ban.
As sad as the incident is, 27 people over 14 minutes is not "hundreds of people a minute."
-Following comments are based on if the media reports are true-
The incident is also the reason we need to enforce the existing laws such as not allowing the mentally unstable access to them. It was reported that Adam was diagnosed ASD and possibly autistic. ASD's tendency towards intense interest and Autisim's potential to disconnect the person from their actions (ie lack of feeling or remorse) is a bad combination of ailments to hand a weapon to.
It was stated that he was denied purchase of firearms (I am not sure on this.) So he then shot his mother and stole all of her weapons and went a rampage.
My understanding is the legal side of the incident worked. Adam then chose to kill his mother and steal hers.
At best I could see this as "failure to secure / properly store" but the person who would be charged with that was killed by the thief.
-Posted here because I am not uncaring, but I hate seeing small children being paraded around as the reason for control. Reality is a criminal killed a person and store those weapons and proceeded to commit more crimes.-
