Which of the following is an example of lawful intrusion?

Lawful intrusion refers to situations where law enforcement officers are permitted to enter a property or engage with individuals based on legal justifications. Exigent circumstances provide a clear example of lawful intrusion because they involve situations where immediate action is necessary to prevent harm, destruction of evidence, or escape of a suspect.

In scenarios involving exigent circumstances, the law recognizes that waiting for a warrant could lead to significant risk, such as the potential loss of evidence or danger to individuals. This principle allows officers to act swiftly and without a warrant when they have reason to believe that immediate action is warranted.

On the other hand, while receiving a tip from a citizen, voluntary statements from a suspect, or observing traffic violations can lead to further investigative actions, they do not necessarily qualify as lawful intrusions on their own. They may provide reasonable suspicion or probable cause, but exigent circumstances specifically underpin the legality of an immediate intrusion without a warrant. This distinction is crucial in understanding the boundaries of lawful law enforcement actions.
