In most cases, pickpockets operated depending on the opportunities they got: if they saw someone wearing a silver watch or with a handkerchief bulging out of their pocket, the pickpockets took the item. This means that the theft was, in such cases, not premeditated. However, some pickpockets did work as a gang, in which cases they planned thefts, even though they could not be sure of what they would get (Defoe's "Moll Flanders" gives several examples of how pickpockets worked as a team or on their own, when the eponymous character becomes a thief out of need).
