I'm not a US citizen - I one of those people who live in the mythical country to the north of you.
I do have a question for all Americans - when are you going to stand up and put an end to this? Everything is already in place for you to be stopped at ANY point for a full TSA style search and presentation of papers or you cannot go about your business. Given that this is now a fact... when are you going to roll that wheel off your backs and become, once again 'the land of the Free?'
