Most states define robbery as theft/larceny of property or money through the use of physical force or fear/intimidation against a victim. Where a deadly weapon such as a gun is used, or the victim suffers an injury, the robber may be charged as “armed” or “aggravated.” Unlike burglary, the crime of robbery almost always requires the presence of a victim who suffers an actual injury or is threatened with bodily harm.
For example, “Joe” approaches “Bob” from behind, demanding Bob’s wallet while pressing a hard object into his back. Fearing that Joe has a gun or other weapon, Bob gives up his wallet. If Joe did use a gun or deadly weapon, or if Bob suffered an injury, the charge would likely be elevated to “armed” or “aggravated” robbery.
