Big guns in confined spaces

This is really no laughing matter but me being me I saw an amusing side. Al-Jazeera news has been handed a videotape claiming that a group has captured 20 Iraqi soldiers. I saw this on the TV within the last couple of hours and it's the image that concerns me.

Look at the photo. It's a small room. The guy to the right of the picture is pointing a rocket-launcher at the captured Iraqi soldiers. Presumably he's "guarding" them. Now what if one of them makes a break for it? What's he gonna do, SHOOT?
