CARTOONIST Signe Wilkinson blames the National Rifle Association for the Virginia Tech massacre.

But a psychotic named Cho did the killings, not the metal object in his hands or the NRA. He was able to buy the gun legally because he had no criminal record, and gun dealers aren't mind readers.

Any criminal or creep who wants a gun and has a record can still obtain one illegally, very cheap. The problem isn't bad guys with guns, it's good guys without guns.
