Shooting skillfuly takes practice and discipline.Proper gripping of the weapon must be learned, proper breathing, knowing how to acquire the proper sight picture, blocking out distractions, proper maintenance and care of the weapon.
If the punks who did drive bys had learned to shoot, there would be no one injured besides the intended target.
Any idiot can pick up a sword, gun, knife etc. and harm others indiscriminantly. It is not the weapons fault, but the brainless moron wielding it.
