How can human trafficking of migrants be stopped?

I think the most important way to stop migrant human trafficking is by offering migrants protection. Many migrants (especially those that are undocumented) feel that they cannot report crimes committed against them, for fear of being deported. Many have also faced discrimination from the police or other law enforcement agencies and feel that they will not be protected or listened to if they report a crime. Human traffickers use this to target migrants. To stop human trafficking of migrants, we must first ensure that migrants will be listened to, protected, and not deported if they report a crime. If migrants were regarded as the rest of the citizens by law enforcement agencies, they may not be targeted by human traffickers.
