Now I'm curious. What would happen when you are being sworn in and when they say ".....and nothing but the truth, so help you God"... and you say No?
I know they wouldn't put you on the witness stand, but what would be the next step?
If you are the accused you can plead the 5th. Even as a witness you can take the 5th. But what if you simply don't promise not to lie?
An oath, apparently, is just a formality. It means nothing if the person swearing
the oath has no honor. Look at Congress, they all swear an oath to uphold the Constitution. If they all did as they promised, how far apart could they be?
On the other hand, it's against the law to lie to the FBI, why not the same thing for lying to Congress?
