Schneier removed from TSA oversight meeting at TSA request 
Why is Schneier presumed to be the most effective critic of the TSA? The body scanner program in particular has been roundly criticized by civil libertarians (both conservative and liberal), has generated credible concerns from professional scientists as to health risks, and has been repeatedly demonstrated by physical security experts to be ineffective.Schneier is an effective writer, particular when his audience  comes with built-in respect for his accomplishments, but his broad disdain for virtually all of airport security† probably reduces his effectiveness in making a case to the wider public. He's easy to caricature, and traffics professionally in an image of "security muckraking" that suggests he'd oppose the TSA no matter what it does.† A disdain I share, mind you.
