This is what Oscar Pistorius said in an affidavit:

I sleep with my 9mm under my bed. I woke up to close the sliding door and heard a noise in the bathroom.
I was scared and didn’t switch on the light. I got my gun and moved towards the bathroom. I screamed at the intruder because I did not have my legs on, I felt vulnerable. I fired shots through the bathroom door and told Reeva to call police.
Your legs might help you on the field, but don't expect them to do the same in court.

On another note, the one thing about this case is that it has introduced America to lots of black police officers.
