This is classic Joe Klein:

Over the past few weeks, I’ve asked Constitutional Law professors from Harvard, Yale and the University of Chicago about the immunity provision. There are differences of opinion—no one is thrilled about immunity, to be sure—but the bottom line is, essentially, that this is a lesser issue diverting attention from the passage of an important law.

The importance of telecom immunity is NOT a legal issue that gives law professors any special insight on its relative importance. Your opinion or my opinion is as valid as yours or mine.

But what is more interesting is that Klien basically falsely states what one of the two law professors he actually quotes says. David Barron of Harvard did NOT agree with Joe Klein that telecom immunity should be allowed. He said the opposite. Cass Sunstein, who has supported the bush Administration's illegal activities for 7 years now is not surprising when he does so again now. That is like asking John Yoo on this issue frankly. And he does not disappoint Klein here. Sunstein has been an embarrassing shill for the Bush Administration on FISA since day one. His opinion on this to me is less than meaningless.

In short, a classic Klein post, ignorant, misleading and wrong.
