I found out that you can easily steal. The NPC that is in the area can be distracted by talking with another char and after the first char stole all things you can move him out of the NPC area. After ending the conversation the other char gets accused and can be searched (without the items that were stolen). After the dialogue no other char will be accused anymore.
The accusations only starts when you steal something that is in the area of a NPC. And only those stolen items can be found by the NPC. If the NPC comes back to his area and "searches" for his items it will accuse one guy next to him and want to search his pockets.
