To push criminal sanctions is to invite retaliation. I sense, however, in AG Ashcroft a curious streak of Puritanism that may encourage him to throw caution to the wind and prosecute. I view this as a good thing with some bad fallout. It will remind everyone that the immunity is not complete and the veil can be pierced. Sandy Berger will never see jail time, though. That would be unseemly and would signal all out partisan warfare.
Your blithe assetion that there are different rules for the in-crowd may be true- but it is still destestable. I suspect that Thomas Jeffereson and our Founding Fathers would have advocated armed insurrection against such a system.
And what we've got now is not partisan warfare?
Oh, well, perhaps you're right -- it takes two sides to make war, and thus far we've only got Dems on a bloody warpath, and the Pubbies hiding under desks, fearing to be "unseemly" as Rome burns.
