18 U.S.C. § 2071(b)— specifically directed at custodians of public records. Any custodian of a public record who “willfully and unlawfully conceals, removes, mutilates, obliterates, falsifies, or destroys (any record) shall be fined not more than $2,000 or imprisoned not more than three years, or both; and shall forfeit his office and be disqualified from holding any office under the United States.” While the range of acts proscribed by this subsection is somewhat narrower than subsection (a), it does provide the additional penalty of forfeiture of position with the United States.
