Which crime does not require any evidence of a weapon being present?

Robbery is characterized as taking property from a person through intimidation, threat, or use of force, which conveys a potential for violence but does not necessarily require a weapon to be present at the time of the crime. The act of robbing involves the direct confrontation of the victim, and that intimidation can happen through the mere threat of violence, thus making evidence of a weapon unnecessary.

In contrast, burglary typically involves trespassing into a building with the intent to commit a crime, and while it can involve theft, it does not inherently include the confrontation aspect of robbery. Larceny refers to the unlawful taking of someone else's property with the intent to permanently deprive them of it, and it similarly does not imply any confrontation with the victim. Extortion involves obtaining something from someone through coercion or threats but is not limited to immediate confrontation, either.

Hence, since robbery is primarily concerned with the act of confrontation and the intimidation involved, it does not predicate the physical presence of a weapon for the crime to be valid.
