I watched 20-20 the other night, and the entire show was about guns and gun control in the US. While I realize that they tend to sensationalize things somewhat, if only a fraction of what they reported is true, it's damn frightening.
The most interesting thing to me was this scenario they set up using college aged students. Each of the 6 of them had varying experience with guns and shooting, ranging from none to considerable. In the scenario, they had each of them attend a lecture having to do with guns, while they were each supposedly "armed," their weapons in holsters at their sides, and while they thought they were loaded, they were only loaded with a paintball sort of thing. During the lecture, they had an armed shooter bust into the room and begin aiming his weapon and shooting. Of the six of them, even those with gun experience, several of them couldn't even get their guns out of their holsters. Others shot or nearly shot other innocent lecture attendees (actually, they were law enforcement workers posing as students). Only one of the 6 managed to get a shot off at the shooter, and that was only a glancing shot off his arm that would have been a flesh wound at best.
The moral of the story, obviously, is that in a crisis situation, guns aren't of much help to ordinary citizens, even those with considerable shooting range experience, and, they can actually do a great deal of harm by shooting innocent bystanders. They spoke to many police officers who confirmed this, and they said that they need regular training on a regular basis in order to keep their shooting skills up to par, and to retain muscle memory for quick movement in a crisis situation. It was really interesting, and kind of disturbing at the same time.
The episode can be seen here, if anyone's interested:
