Remedy for a Problem

In regard to organized crime preying on immigrants, David comments:

[T]here definitely is a problem since migrants won't denounce crimes against and officials in some parts of the country show a crushing indifference toward launching investigations.

That's a good point, and it's something that immigrants mention, too. That makes me wonder if an anonymous denunciation system would be feasible for Central American immigrants. Of course, there would be some significant practical barriers; many crimes against immigrants take place in remote locations, the kidnappers of immigrants are unlikely to remain in the spot for long, and, whatever the assurances, convincing vulnerable immigrants to denounce their attackers rather than simply move on is always going to be an uphill battle. Nonetheless, this doesn't strike me as an impossible problem.
