Which of these individuals is not guilty of unlawful entry into a school building?

In the context of this question, the key to understanding why the choice regarding someone attending a non-school event is correct lies in the concept of lawful entry based on the purpose of the visit. An individual attending a non-school event is typically there with the permission of the school and is engaged in an activity that has been sanctioned by the administration. This means they have a legitimate reason to be on the premises, thereby not constituting unlawful entry.

Conversely, the other individuals listed—an enrolled student, a parent of an enrolled student, and an employee of the school—are all associated with the school in ways that grant them lawful access to the building. However, their access is based on their status, and any behavior outside of the expected or permitted conduct could potentially lead to circumstances categorized as unlawful entry.

In contrast, a person attending an event that is explicitly approved for gatherings at the school (like a sports game or community meeting) does not fall under the same scrutiny and is not violating laws regarding entry. Thus, they are not guilty of unlawful entry. This distinction helps clarify why this choice stands apart from the others.
