Why Libby Lied to the Grand Jury

Think about it.  Let's assume a) that you were part of a conspiracy with the VP to create intelligence in order to sell the Iraq war, b) that you were part of a conspiracy with the VP to discredit Joe Wilson via leaks about his wife, and c) a CIA agent died as a result of your leak (something Libby would know if it happened). If all of these things were true, and I am sure of a and b at least, if I were Libby I would try to get away with lying about it.  Because these three things taken together are clearly treasonous. Far better to take a chance and lie and possibly get away with it, or even accept a perjury indictment.  But no way would you want to admit anything that indicated you were part of a treasonous conspiracy like this. It's more than trying to cover up for the VP, he has to cover up for himself.

I think someone died as a result of this. If so, wouldn't you lie if you were Libby? How could you possibly tell the truth about your role in this? Just think about it.
