Did Lay and Skilling lie under oath in the Enron "self-defense" portion of the trial...? Well lets hope not!
Consider:
There is a reason that "most" defendants don't take the witness stand on their own behalf...and that is because it's their attorney's DUTY to see to it that LIES ARE NOT TOLD UNDER OATH...IN TRIAL.
If a Defendant wants to commit perjury, and absolutely insists on it, ...it is the obligation of their attorney to resign immediately...and not be party to the perjury; or to the suborning of perjury.
You've probably seen cases where an attorney will resign "mysteriously"....? Well, that could be the reason....
A defendant simply can not "throw it against the wall and see if it sticks" in most criminal cases...
And that applies to low level cases...AND HIGH LEVEL WHITE COLLAR CRIMES...EQUALLY.
I personally found Lay and Skilling to be very bad witnesses on their own behalf...but when your back is to the wall...anything goes I suppose.... A just result by this jury.
