The informers who quit the witness protection program really have nothing to fear and they know it. All of the men that would have given the order to whack them are in jail and or dead. With DNA and video cameras in the sky and on every street corner, the shooter would be captured in a week and the feds would bury them in super-max to make an example of them. It makes me laugh when guys leave witness protection and act like their life is in constant danger, From who? Who is left to give the order and carry it out? I would be more worried about an IRS audit if I was in their shoes.
