i think you are retarded if you think the FBI is allowed to execute someone (laying in bed, completely harmless, in custody) without judge, jury or trial. =)
who says they are allowed? or sanctioned? branches like these are under the radar. people who could say no to things like (out of the "goodness" in their hearts) normally doesn't know about this. and besides, not everybody is a straight arrow. not even the good guys (as Reynold's character show). i don't even get why you think pulling the plug was an "execution". i see it as getting rid of the cause of the entire mess (that got his partner needlessly killed, among countless others). he felt betrayed by his superiors, and so he rebels and betrays them as well. letting father and son die* would make a huge blowback and would probably be an act of vengeance of sorts.
* - (instead of killing father and son; their deaths are indirect, as they died because their life-support failed, which failed because he pulled the plug as opposed to throttling them)
ferofax i wasn't saying pulling the plug was an execution, i was saying doing the heart transplant was.
They had the Swede that Sperazza first hired to do the transplant, presumably in custody. I think Deputy Director Locke and his men were just going to "turn a blind eye" while the Swede did what he was hired to do. And then get all the info they could out of the healthier Sperazza.
