Then there is the case of Jeffrey Doucet, shot by Gary Plauche in the Baton Rouge airport. Doucet had kidnapped and sexually assaulted Plauche's 11 year old son. He was caught and was being returned to Louisiana. Plauche hid in the airport and blew Doucet's head off as he walked by in custody. This happened March 16th, 1984.
Plauche offered a guilty plea to manslaughter and was given 5 year's probation. I would have given him a medal.

I agree. I am so glad this young man is doing so well. He must have had great parents.
