I don't agree with most of this post. Kinetic energy and penetration mean a lot in the ballistics world.How would oneexplain howpolice officers have died after beingshot intheir bullet proof vest even though the bullet did not penetrate? The force which a bullet hits an objectcan do considerable damage even if it does not penetrate.

It also looks like this article was written for the self defense crowd. I have little doubt that most of these cases are from small caliber pistols or had much to do with the dress of the subjects. I doubt that there are several people that are walking around with 22, 25, 32 and possibly 38caliber lead in them.There are too manyvariables when youtry to study ballistics on humans.

There are also datails in the article that are left out of the examples.The major makeup of animals including humans is water. I don't believe that the Hydrostatic Shock sections takes into account that you areessentially displacing fluid in a closed container of a fixed size. Try shooting a capped two liter of Coke or agallon of water then shoot one thatis empty.You will see a huge difference.
