If you observe someone committing a crime on property where you lack the authority to arrest, what should you do?

When witnessing a crime occurring on property where you do not have the authority to make an arrest, the most appropriate course of action is to call the police immediately. This response is based on the understanding that a trained law enforcement officer is better equipped to handle the situation. They have the legal authority to detain individuals and conduct investigations, which you do not possess in this scenario.

Engaging directly with the individual by detaining them or confronting them can escalate the situation and potentially lead to personal harm or legal repercussions for you. Informing the property owner may be beneficial but is secondary to ensuring that law enforcement is alerted to the ongoing criminal activity. Their immediate response is critical to address the incident effectively and maintain safety on the property.
