To answer the question about the guns camera in the Shar, the simple reply is that very little footage was taken. I thinks Andy Auld's might be the only one.
The problem was, if I remember correctly, the switching for the camera. It was wired in such a way as to make a weapon's stuff up highly probable and most of us didn't have the time or inclination to include camera film in the already quite busy environment. I wasn't as simple as raising the safety catch and expecting the camera to run. (Perhaps somebody with a better memory can enlighten us.)
