Only tattooed ones. That was Ilse Koch, one of the ultimate serial killers, since she was a guard and the commandant's wife at the Buchenwald concentration camp. She got off quite lightly on a retrial, on the basis that she hadn't actually got anybody killed for the purpose. Being a profoundly defective human being isn't on anybody's statute book.

In a programme of testing of the wounding power of bullets, some time ago, it was found that bones varied a great deal. Pig bone, for example, was spongy and resilient, and provided a poor indication of the effect on men of military age, although we get more porcine as time goes by. It was found that a variety of alpine goat was about right.
