I hadn't run across these numbers before, although I'm troubled by the use of the phrase "innocent person". The MP shot by the cop in the other thread could be classified as an "innocent person" because he had not committed a crime, but the cop certainly hit what he was aiming for. The term "innocent bystander" would alieviate my concerns about how they collected their data, but by and large I'll accept that cops are more likely to miss. Certainly circumstances are going to dictate a lot of these numbers (i.e. shooting a hostage being used at a distance, needing to fire after a high-speed pursuit, most civilian shooting happen at closer quarters than police shootings, etc.).
I still think that you pulled the 50% number completely out of your ass, and I don't see where you've proven that point.
