This, as usual, from the New York Post:

"For substance, turn [from Time] to Newsweek. The cover story on Thomas Tamm, a Justice Department employee-turned-whistleblower on the Bush administration's wiretapping program is far more compelling than the entire Time issue. Newsweek writer Michael Isikoff got Tamm to speak on the record against the advice of his lawyers, and the story he tells is not an uncommon one among whistleblowers: extreme courage, bolstered by a keen sense of moral obligation, creates personal and professional upheaval that threatens to destroy everything he's worked for. Or, as Isikoff writes, "Sometimes the thinnest of lines seperates the criminal from the hero."
