The problem here is lack of training and lack of respect for firearms. The kid should have known, first of all, never to point a gun at anyone unless he meant it.
Second, clearing an auto is a 3-step process:
1. while pointing the muzzle in a safe direction, drop the magazine (not “clip” - idiot journalist alert)
2. rack the slide to clear the chamber
3. visually and manually check the chamber to make sure it’s empty
All the safety devices in the world can’t overcome stupidity and ignorance.
I give the journalists a pass on this one. Many gun sites also use clip instead of magazine.
