Meditations on Violence. The subtitle is A Comparison of Martial Arts Training & Real World Violence; almost done with it; good book. Lots on training, types of violence, staying OUT of violence, problems with lots of training, types of bad guys(types of predators, general dumbass troublemakers and such).

He has this on the subject of shooting:
There is a statistic floating around: "At seven yards or less, officers miss 92% of the time." I've heard this statistic from our police academy and in training sessions with the U.S. Marshals. I have no idea where it came from and I haven't been able to find the source. However, NYPD statistics from 1994-2000 show a hit percentage at zero to two yards of 38%. Think about that- a trained officer at contact range to six feet away misses 62% of the time. At the firing, range, it would be almost unheard of to miss at six feet.

At three to seven yards, they missed 83% of the time.
