David Kaczynski, the brother of Unabomber Theodore Kaczynski, listens to a question before his talk on Tuesday, March 28, 2006, in Albany, N.Y., at the Center for Disability Services. Ten years after Theodore Kaczynski's arrest, the once-friendly brothers are worlds apart. One is in prison for life. The other talks to crowds as an anti-death penalty lobbyist and offers a picture of his infamous brother as a human being suffering from mental illness. (AP Photo/ Jim McKnight) Date: 28/03/2006
