Anyone else find it weird they included his social security number (page 5)? With the amount of detail they included it seems as though it would be fairly easy for someone to use any FBI file on a deceased person for fraudulent purposes, ID theft, or accessing accounts at companies who may not realize he is deceased yet.
The SSA would love to insist that redistribution is illegal, because the price of the SSDMF is outrageous and a cash cow, but they don't have a legal leg to stand on. The SSDI is public record, and because it's a database with no creative element, it's not copyrightable even if it were compiled by someone other than the government.
Social Security numbers are too widely used to really be regarded as secrets (how many government, bank, employer and call centre staff have access to yours) or to be used as authentication. They are a pretty good identifier of who is being referred to though.
