Somebody gets goofy and these people immediately have their hands out asking for money.
It's For The Children™.
Just how is the NICS Bill supposed to prevent something like this? He was already unable to buy any kind of firearm legally; obviously the law was unable to prevent him from obtaining them. The problem, in this particular case, was a bad home environment; it seems he and his brother had been in and out of trouble for quite some time. As long as there are people growing up under bad conditions, you are going to have violence. Blaming a piece of metal and making "feelgood" laws does not solve problems.
Just my opinion.
