I think you’re thinking of sex trafficking. The John being a tourist is orthogonal to the prostitute being a victim of trafficking. Many sex tourists visit Germany, for example, where prostitution is a safe, unionized profession.

Yeah, I'm not talking about Germany. We're talking about why border patrol might investigate something.

Highly naive picture of germanys pragmatic situation - basically nobody is registered much less unionized and trafficking is everywhere.
