Dust for Prints if you get a letter like this one:
"A bogus letter circulating in South Carolina, purporting to be from the NAACP, threatens the arrest of voters who have outstanding parking tickets or failed to pay child support. The NAACP said Friday the letter is a scare tactic and called for an investigation."

Not that it is likely that anyone reads this blog, or, in particular that anyone will read this blog and then get a letter like that, which, I would say constitutes the crime of attempting to deprive the recipient of his or her civil rights.
