To my knowledge there has never been an instance where this was improperly applied. It's just another case of lying Democrats.
Some of our European friends picked up on it as well as static about potential hijackings of US aircraft from our own sources.
Of course with a government our size, twisted beyond redemption, it took a while to connect the dots and act. But hey, it’s not like we don’t have excellent oversight on our immigration laws and crack down on expired visas. No, we must resort to laws which might be abused by the wrong civil/public servants in order to not rock the illegal immigration gravy train (Just one of several instances that could have slowed down/hindered 9/11).
