Roger Cohen pays tribute to investigative journalist Seymour Hersh -- and takes a well-aimed pop at some of the more self-important voices in the blogosphere:

"We live in a time of danger, moral uncertainty and virulent division in which the MSM have become an easy target.

"But it appears critical, now, not to be cowed.

"The values of Hersh - against-the-grain, inquiring, skeptical, painstaking - are still what make the press an essential check on power rather than an accumulation of voices shrieking with righteous indignation in the electronic wilderness."
