From the Preamble (public information)
FinCEN does not expect the information obtained pursuant to the beneficial ownership requirement to add additional requirements with respect to Section 314(a) for financial institutions. The rule implementing Section 314(a), set forth at 31 CFR 1010.520, does not authorize the reporting of beneficial ownership information associated with an account or transaction matching a named subject.
If you were to get a "hit" on a beneficial owner you simply don't have enough information for it to be worth law enforcement's time; i.e. they probably knew that much already.
In this world you must be oh so smart or oh so pleasant. Well, for years I was smart. I recommend pleasant.
