the "golden shield" isn't

"For an academic to hold extreme views of executive power, of course, is arguably a matter of academic freedom, and even a form of creative theorizing that one might admire. (Although some of Yoo's Berkeley colleagues, such as economist Brad DeLong, among others, have described his theories as reaching so far beyond the bounds of creative academic theorizing as to be simply dishonest and undeserving of that protection.)

But Yoo's memos at OLC were not part of an academic exercise; they were making policy. Setting aside for a moment the potential culpability of Yoo himself, the more important point here is that, as the inspectors general report makes clear, the White House specifically sought him out and excluded his superiors, ignoring the usual chain of command in the Justice Department, apparently because they knew that John Yoo would give them the legal opinions that they wanted to hear. - DAPHNE EVIATAR
