I guess my perspective on this is blurred by me being German, or in a broader context, European. Our institutions are not really known for laying such "traps". I guess it's different in the world of the secret services (as opposed to traditional law enforcement). And well, yes, in the US there's the DEA, maybe the FBI, too, but I always thought that their ability to legally create "dodgy banks" or similar are kind of a Hollywood thing.

In general, the US seems a lot more willing and capable to really invest capacities in fighting money laundery than any agency I can imagine here in the EU.
