What offense has been committed if a kid on a skateboard steals a radio from a bench?

The correct answer is theft, which involves the unlawful taking of someone else's property with the intent to permanently deprive them of it. In this scenario, the kid on the skateboard stealing the radio from the bench demonstrates this specific crime. Theft is characterized by the absence of force or threats against a person; the act is simply taking an item that doesn't belong to the thief.

Burglary involves entering a building or structure unlawfully with the intent to commit a crime inside, which is not applicable here since the act occurred outside and did not involve unlawful entry into a building. Robbery requires the use of force, intimidation, or threat to take property from someone directly, which again does not apply as the theft of the radio occurred without any confrontation. Assault involves causing physical harm or the threat of harm to another person, which is unrelated to the act of stealing an object from a location. Therefore, theft is the most accurate description of the offense committed in this situation.
