Now hold your horse, i am not saying that the US should ban guns or make stricter laws. This topic is about how they are used.
I have been watching a lot of series recently, and it made me think, that even if it is fiction, one thing stays consistent. Killshot.
They always aim for the chest because it is the biggest target, but in my opinion the legs aren't so hard to hit. This year a man was killed while walking to a police car, a sergeant in the car shot him down (a woman by the way) and said, "He was walking with a purpose"
Shot in the chest, DoA. She could just as easily have aimed the gun at him in order to stop, or shot him in the leg to get him to stop. If your argument is that the leg is always moving when walking or running, it always circles back, So anyone who knows how to hit a target can shoot for the legs.
In my opinion, having guns is not a bad thing, but going for a killshot with every chance you get makes me mad.
