What is a common indicator of human smuggling or trafficking?

A common indicator of human smuggling or trafficking is indeed the presence of suspicious identification. This can include false or altered identification documents which often indicate that individuals are being transported through illegal means. Individuals who are victims of trafficking may not possess valid IDs, or they might have documents that do not match their identity, which raises concern about their situation and the legality of their transport.

Recruitment and transportation of individuals is also a significant aspect of both human smuggling and trafficking; however, it is a broader concept rather than a specific indicator. Unusual behavior, while potentially indicative of trafficking or smuggling, can be subjective and vary widely based on context and culture.

The correct response encompasses an understanding of specific, concrete evidence, such as suspicious identification, which is often crucial for law enforcement to identify potential victims or smugglers effectively.
