What's it all about?

This story came out this morning, and I've been trying to figure out why I was having mixed reactions to it.

WASHINGTON - The FBI violated the Constitution when agents raided U.S. Rep. William Jefferson's office last year and viewed legislative documents in a corruption investigation, a federal appeals court ruled Friday.

Finally, it came to me. On the one hand, it seems to me very refreshing that the Court stepped in and upheld Congress in a battle between Congress and the White House.

On the other hand, the Court let the Justice Department keep the stuff they got from Jefferson's office that wasn't Congressional stuff even though the raid that enabled them to get those documents was unconstitutional. I'm hoping that doesn't mean that DOJ will be able to use those documents against him in Jefferson's trial, but I suspect it does. If they are, what's to stop the DOJ from raiding Congressional offices all the time? They get the personal documents they want to use in a trial, and meanwhile, Bush's boys get to review the official Congressional documents that will eventually have to be returned in order to see what the Dems are up to. It's symbiotic.

Shouldn't there be some sanction to those who knowingly violate the Constitution?

Now, I don't want to suggest by any of this that I condone Jefferson's behavior. From everything I know, the man sounds like an utter sleazebag.
