The jury is pretty much in on this one, but for those holdouts who still aren’t convinced that Fred Thompson is running, here’s your smoking gun:  Thompson is leaving “Law & Order.”

“I’ve spoken to Fred today, and although he told me he has not made a firm decision about his political future, he felt that given the creative and scheduling constraints of the upcoming season, he asked to be released from his responsibilities to the show,” “Law & Order” creator/exective producer Dick Wolf said Wednesday. “I will sincerely miss working with him on a regular basis, and I obviously wish him the best of luck with whatever the future holds.”

This headline opens a whole new avenue of questioning.  How will Arthur Branch be written off the show?  Will he just leave town?  Will he be killed off?  Will Jack McCoy take over as D.A.? America wants to know.
