I don't know and don't care why Tom Ridge resigned. The DHS has nothing to do with interrogation of terrorist detainees at Gitmo. This was done by the CIA, a completely different agency of the government. Why can't you answer my question? Why do you have to switch the topic to Tom Ridge?
Please tell me why you can rationalize how an administration put out false warnings based on known false information? Did they think people were not smart enough to discover it was false information? You know, that may apply if we lived in ancient times, before information technology prevailed. It may apply for pre-WWII Europe under the Gestapo, where the only information available was the propaganda put out by the government. But it simply defies logic in the day and age we currently live. There is simply no basis in reality for what you are claiming.
Enough people were duped by it, but not Tom Ridge.... He quit over it!
