Other forms: robberies
A person who steals money from a convenience store by claiming to have a gun under his shirt is guilty of robbery, or using a violent threat to take something that doesn't belong to him.
Whether a criminal wields a weapon or just threatens to hurt someone while stealing from that person, he is committing robbery. Robbery is different from burglary — breaking into a house or building to steal — because it involves a threat of danger to a person. Carjackings, stick-ups, and muggings are all different kinds of robbery.
