"Please Remove Your Shoes" is a revealing documentary about broken government process. It is also an empathetic story about a half dozen public servants who try to fix it. And it is a familiar topic to all of us who have flown in the last fifteen years:the security routine at the airport, first the FAA and now the TSA. The film examines the period before 9/11 and the current situation nine years later and asks the questions that make Washington squirm: Are we really any better for all our money spent? Or, is it safe to say that nothing has changed?
