Former Terrorists? - Please explain

The term "former terrorist" is getting thrown around a lot these days. Much of it has to do with the Barack Obama and William "Bill" Ayers connection.

I wonder though; how do you go from being a terrorist to a former terrorist? Is there an application you fill out? Are you forgiven after so many years? 

I always thought, "once a terrorist always a terrorist" but I guess I was wrong.

Maybe given the certain political "situation" it's the politically correct thing to say. We certainly wouldn't want to offend anyone who's bombed the Capital, Pentagon, and killed policemen. 

If anyone knows the process for becoming a former terrorist please comment!
