I was traveling alone and in a wheelchair from Washington, DC to Portland, ME. I had to "walk" through the "radiation machine" twice....never heard of that but then, it has been almost 40 years since I have flown and had no idea what the TSA even was other than that they sometimes did patdowns. From what I read, I went through 3 of these patdowns in addition to twice through the radiation. 2 of them involved the groping and even slight penetration in the stories I've been reading. I am filing complaints although I doubt anything will come of it. I am an activist and the TSA was asking tons of questions as to why I was in Washington and what I had done, which hotel I stayed in, etc. Didn't know they could "interrogate", too. Can they legally do so? They said I was a 2-alarm...does anyone know what that means. I asked and kept asking but no one listened or responded. Could that have been the reason they thought they had "probable cause". My wheelchair became an object of real interest- they broke it in the process of removing parts so they could take samples of a supposed "explosive". Asked tons of medical questions. Has anybody made complaints and to who? Results?
