I expect that some criminals using LR (it's safe to assume there were at least a few, right?) will resort to other methods of moving money that impose more risk to themselves.  It seems to me that statistically, they should get caught sooner.

IMO if even one of them is involved in human trafficking, the whole bust is worth it.  I wouldn't be surprised to see more people getting caught laundering money now that the cover of LR is gone.
