What does “reasonable suspicion” imply during a vessel boarding?

“Reasonable suspicion” during a vessel boarding implies a belief based on facts or observations. This legal standard requires that the boarding officer has specific, articulable facts or circumstances that suggest potential illegal activity. It is not merely an instinct or a hunch; rather, it is grounded in tangible evidence or behavior that can lead a law enforcement officer to suspect that something inappropriate may be occurring.

In practice, this means that a boarding officer must be able to articulate the reasons behind their suspicion. For example, if a crew member is behaving nervously or a vessel is operating in an unusual manner that deviates from normal operations, these observations can contribute to establishing reasonable suspicion.

This concept is crucial in maintaining legal and constitutional safeguards during boarding operations, ensuring that officers do not engage in arbitrary or discriminatory enforcement actions. The ability to point to specific observations helps justify the boarding and any subsequent actions taken based on those observations.
