In the trial, the prosecution brought up an incident that happened earlier at a restaurant. Seems that Pistorius accidently shot a friend in the foot when a pistol discharged inside a Johannesburg restaurant. One friend passed a loaded gun to Pistorius under the table. The gun was loaded with one round in the chamber and, apparently, the safety off. The gun went off and shot another friend in the toe.
You have to wonder about a friend who would pass a loaded gun with one round in the chamber and the safety off to another friend under the table. Duh! What could possibly go wrong? You also have to wonder about someone who pulls the trigger to see if a gun is loaded. A good practice when handed a weapon is to check the safety. I don’t think Pistorius is the type of person who should own a gun.
Having said that, I recall that when I was in the military, we had a similar incident. A soldier was turning in his 45 cal. pistol. The armorer told him to make sure it was not loaded. The soldier pointed it at the floor and pulled the trigger, wounding two bystanders.
