So the CIA tells us that Osama was planning attacks on "soft targets" like train and bus stations and stadiums, a few days after the DHS sent out a press release with the same claim. If you oppose the expansion of expensive and dangerous full-body x-ray machines to these new locations, you must be a fellow traveler of al-Qaeda.
UPDATE from Wendy Moore:
It's also interesting that the CIA reveals this threat just a couple of months after a lot of negative TSA publicity was generated over the story of train passengers being harassed AFTER arriving at their destination (see here and here). Not to mention it being only about one month since the Amtrak police chief ordered TSA off Amtrak property.
