I love the idea of a shield law; I don't know of any journalist who doesn't love the idea of a shield law. It's all in the details. Some of the shield laws that were floating around sounded good, but when you looked at them, exceptions or exclusions or broadness in the language really invited some problems.

You have tens, hundreds of thousands of people in government, and just as many among contractors, who feel totally comfortable writing at the top of the document "internal use only," "official use only," and a million other synonyms, all of which amount to "none of your business" to the public.

An attitudinal sea change. I think that's the hardest one to fix. Presidential directives, bills, provisions can all be rescinded, repealed, amended, but attitudes linger. The hardest thing is going to be to try to reverse an attitude, a bunker mentality that equates secrecy with either security or heightened efficiency and that regards transparency as an invitation to mischief and trespass. This default position of operating in the shadows is going to be somewhat appealing to whomever inherits office.

Every effort is made to control information. Secrecy is just one of the toggles on their control board. The mindset is in place, and they've done a lot of hiring over eight years, not just political appointees. And they've done a lot of firing or driving people out who might have countermanded or resisted. So, institutionally, it's not going to be simply a matter of flipping the switch to undo it. You're going have to bring in people dedicated to transparency, and you have to demonstrate that there are rewards for candor.

A one year study by the Washington Post has documented 620 cases in which experimental drugs have been implicated in the deaths of cancer patients....And they amount to merely a fraction of the thousands of people who in recent years have died or suffered terribly from cancer experiments.

There's no faster way or surer way to consolidate power and disenfranchise critics than to operate in secret. So this plays squarely into the promotion of the unitary executive. That's one factor.
