O. PISTORIUS: This was my very first motorbike, a four-wheeler. And I got sick of it after a while and got a bigger one. But this was so much fun already.
CURNOW (on camera): So you have always been a speed freak?
O. PISTORIUS: Yes, I think so. I have had motorbikes since I was 4 years old and I loved them.
CURNOW: It seems your parents were amazing with you.
O. PISTORIUS: Yes, I think my parents pushed me to try anything that I liked that my brother and my sister were doing. And they never said because I have got a disability or because I don't have legs that I'm not able to do something.
CURNOW (voice-over): Pistorius reportedly often carried a gun and had a love of shooting. In November of 2011, he posted this picture on Twitter along with the tweet, "Had a 96 percent head shot over 300 meters from 50 shots. Bam."
LOUW: Oscar was always, always a bit of -- I call it scared.
CURNOW (on camera): So you say Oscar was scared. Was it because he had no legs? Did he feel very, very vulnerable? Or was it something different?
LOUW: You know, I have heard a lot of stories in the press, but without these prosthetics, very vulnerable. Only a guy working with these guys and themselves will know how vulnerable they are.
VAN ZYL: I think a lot of people forget the fact that, if he's without his prosthetics, well, he's a mere 3.5', 4' high, maybe.
