Which of the following offenses would fall under excluded jurisdiction for juveniles?

First-degree murder falls under excluded jurisdiction for juveniles because it is a serious offense that typically involves intentional killing and is viewed as a significant threat to public safety. In many jurisdictions, including Illinois, certain violent crimes like first-degree murder are classified as excluded offenses, meaning that juveniles charged with such crimes may be tried in adult court rather than juvenile court. This decision is often based on the nature of the crime, the severity of the harm caused, and the belief that the juvenile poses a risk to the community.

In contrast, offenses like robbery, theft, and vandalism can often remain within the juvenile justice system, where rehabilitation and treatment options are emphasized as opposed to punishment. Therefore, first-degree murder's classification as an excluded offense reflects society's recognition of the gravity of the crime and the potential consequences involved in handling it within the juvenile system.
