You also have to wonder if all of the reams of unnecessary papers that are being filed are a not-so-subtle attempt by reluctant banking staff to prevent USEFUL information to the Feds about suspicious banking activities by potential terrorist groups and individuals from being examined?
This could be like the leftist librarians refusing to cooperate with federal investigators regarding certain books and publications checked out by library patrons, i.e., by flooding the Feds with paper regarding transactions which are not really worthy of review, they (bankers) create a blanket of information which helps to conceal that which OUGHT to be investigated.
Until Uncle Sam comes up with some solid regulations to whittle the stream down at the bank end, if it's easiest and least risky financially for a bank to file, a bank WILL file. If I owned a bank I would do that too, after the whopping fines that the heavyhanded Fed.Guv has levied.
