If you were summoned for jury duty and you didn't show up, what would happen? You'd be in jail!

I thought that was the crown jewel of the reporter's resume - to actually go to jail protecting a source.

You may be less likely to pick on someone if you don't know what's in their briefcase or purse.

Even someone as lowly as an assistant U.S. attorney has to undergo a background check, and you're asked a series of very invasive questions, and you're expected to tell the truth and they're under penalty of perjury. And you're asked those questions so you can't be blackmailed or extorted.

The longer you remain silent, the longer you don't turn over documents, a presumption begins to build that you're withholding something. That's human nature. That may not be a legal presumption, but that's a common sense presumption.

When you go into public service, you understand you're trading something. You want to feel good about what you do, but you're not going to make what people in private sector make.
