60 minutes feature on a mentally ill death row defendant

As detailed here, 60 Minutes tonight will include a segment on a capital case from Tennessee.  Here is the set up:

The U.S. Supreme Court prohibits the execution of a prisoner who is insane, but Gregory Thompson, a murderer whose lawyers and doctors say is mentally ill, may yet be put to death in a bizarre case that has been going on for more than 20 years. Lara Logan’s report, including an interview with Thompson, will be broadcast on 60 Minutes, this Sunday, Nov. 11, 2007.
