What is one of the key indicators that distinguishes robbery from theft?

The distinguishing characteristic between robbery and theft is the use of force or intimidation. Robbery involves taking property from a person or in their immediate presence through threats or actual use of physical force. This element is what elevates robbery to a more severe crime compared to theft, where property is taken without confrontation and without the victim's awareness at the time.

The other options refer to aspects that may apply to theft but do not capture the essence of robbery. For instance, taking property secretly is typical of theft, where stealth is involved, while intent to permanently deprive and taking someone else's property are potential elements that can apply to both theft and robbery but do not specifically differentiate between the two offenses. The critical factor that classifies an act as robbery is the presence of force or intimidation that directly implicates the victim.
