When approached by a man asking for a wallet while threatening harm, which crime is occurring?

In this scenario, when a man threatens harm to obtain a wallet, the crime being committed is robbery. Robbery is defined as taking property from a person through the use of force or threat of force. The key element here is the use of intimidation or threats to compel the victim to surrender their property. This distinguishes it from other crimes like theft, which does not involve such intimidation, or burglary, which generally involves breaking and entering with the intent to commit another crime, typically without the presence of the victim. Extortion involves obtaining something through coercion or threats, usually involving the threat of future harm rather than immediate physical harm during the act of grabbing the property. Thus, the immediate and threatening nature of the interaction clearly categorizes it as robbery.
