The bank robbers are the bank owners. They don't actuually DO anything to make money except move it around. They have so devalued curreny and have been systematically stealing from American business and workers, but their greed is limitless. So now, they have turned cannibal. There IS no honor among thieves. You think Lehmann Bros. and Bear Stearns were accidents?
At least one, and probably a cartel of the money center "investment" banks are a rigged casino. These pirates in suits play the unsuspecting for suckers...and you know what? EVEN PRISON DOESN'T PHASE THEM.
The FBI should be looking for someone of high profile in the financial/investment or political sphere that was vacationing in Paraguay or some other non-extradition country at the time.
