Which term describes someone who is actively trying to gain unauthorized access to a property or building?

Prowler is the term that specifically refers to an individual who is engaged in suspicious behavior, typically with the intent of gaining unauthorized access to a property or building. This term is often associated with stealthy or secretive actions that a person may take while trying to intrude or commit a crime, like burglary or trespassing.

In law enforcement and security contexts, identifying a prowler is crucial because it can indicate a potential threat to safety or property. The focus on the active attempt to access a restricted area underscores the serious nature of their intention.

The other options do not align with the definition of trying to gain unauthorized access. For example, "station detail" generally refers to assigned duties or posts within a police or military context, unrelated to unauthorized access. "Illegal peddling" pertains to the unlawful sale of goods, which does not imply an attempt to access premises. "Food for prisoners" is entirely unrelated, as it merely describes a provision for incarcerated individuals. Each of these terms serves different purposes and contexts that are distinct from the act of trespassing or illicit entry represented by the term prowler.
