Received a copy of Richard Miniter's Disinformation in the mail the other day, and blazed through it in near-record time.
The book's subtitle is "22 Media Myths That Undermine the War on Terror" - and it really is what it claims to be. Myths 12-15 cover the many, many links between Saddam Hussein an al Qaeda. While much of it wasn't new to me, it's certainly handy to have everything gathered together in one chapter.
Pick yourself up a copy, and keep it close to your computer monitor; it makes for a handy reference while you read the news. That, and it's just heavy enough to hit your screen with a satisfying "thwap" when all else fails.
