If you can still the armor of a guy. How come you don't get the things in his pocket. Where does he keep his stuff? Maybe in his underwear :-o ? So when you pickpocket... Where does he keep his things? This is for all the characters in Arcanum.
Have you noticed the two small icons above the victims inventory? Well, there's one with the picture of a human body, and another one with a bag. With those two, you can switch between the guys "pockets" and his avatar.
