(AP) A man who for 12 years served as president of the Virginia chapter of the American Civil Liberties Union was sentenced to seven years in prison for downloading what authorities said was some of the "most abhorrent" child pornography they have ever seen. The prison term for Charles Rust-Tierney, 52, of Arlington, is one year less than the minimum sentence suggested under federal sentencing guidelines, and more than the five-year term defense attorneys wanted. Rust-Tierney said depression and "plummeting self-esteem" led him astray.
