The Sikh Coalition just released the FlyRights app. It's a smart phone app that gives travelers who believe they've been the victim of discrimination by the TSA the ability to submit formal complaints directly from their smart phones.
You should have this on your phone the next time you fly!
Available for both Android and iOS. Makes perfect sense to me that a Sikh organization would be the one to put this together, given all of the idiot-hate that community has received post-9/11.
