In the course of robbing the person the weapon is discovered and taken. Robbers often look to take ALL valuables from a person, though they will want to do so as quickly and effectively as possible. Circumstance would have a lot to do with discovering whether or not a person were armed (CC), whereas OC is readily apparent.How do you know to rob a gun from a concealed carrier?
No question....OC provides someone bold enough to attempt a 'snatch' or 'robbery' with information that benefits the actor in assessing the risk and planning the attack. I would never argue that. But, I do think there is a deterrent factor involved with all but the most daring or confident of criminals.
We will see.
