To be honest about this type of crime, it's very difficult to prove in the first place.
With drug trafficking you can define a network. You may have an individual who's caught with a kilogram of cocaine and you can say they're distributing and you get a 15-year sentence. That's not uncommon when you start dealing with and folding in organized crime, and organizations that participate in crime in an organized fashion.
Building cases when you have multiple victims is still very difficult. Even with presumption, it's still going to be very difficult. You're recognizing these people as individuals and you're recognizing that the crimes that were perpetrated against them, as a victim, matter.
