I am from Boston and I am ashamed to say so. This treatment you received was by low life flunkies who have no power anywhere else in their lives, so they go to work and puff up to compensate. They are taking their whole miserable lives to work with them and know that they won't be held accountable. I would have sent correspondence to every major news network and newspaper in the country. Heck, I would even have gotten Geraldo in on it. He loves sensationalism and would have eaten this story for breakfast.
Stories like yours just eat at me. I am always so careful when going through security, but if I encountered a bunch of idiots like you did, I would have hit the roof. It takes an awful lot to make me mad, but when I do watch out. I applaud you for keeping your cool. I have a feeling not many of us here could have.
