9... "That implies the .223 was converted to full automatic which is doable with a kit and the know-how."

Nope. No "kit" required. A simple file on the bent and Bob's yer assassin. I can show you how to do it in less than five minutes.

But, such modifications? To do what he did? Not required. Any marksman can kill anthing he wants to kill with any weapon. It's not about the weapon... it's about the the human who pulls the trigger, whatever trigger, whatever weapon.

What IS required is some REALISTIC GUN LAWS damnit! I just weep at the fact that that the gun-nuts oppose the anti-gun nuts and vice versa. Could they all just realize people... CHILDREN!... are dying?
