if the only two choices on the plate are "lie to the court" or "assist in sending an otherwise innocent man to prison for defending his life/family" well.. that's an easy choice for me. Even easier if it's "lie to the court or send a man to his death for (carrying a weapon, owning the wrong book, having the wrong faith/etc etc etc)." You bet your sweet Yankee tuckus I'd lie.
What bothers me about this statement is the chronology. You have to lie to the court well before you know whether or not the man was defending his life/family or any other details of what he is being charged with. Or do you plan on blindly lying to the court in all cases so you can get on a jury to sabotage the verdict.
