I don't think you would see something like that happen. That goes against all our beliefs in this county. With the wrong politicians in, you possibly could see that. However, with George W. Bush, that wouldn't happen. He is a believer in our countries freedoms. What I do think could happen is that anyone who is not a citizen of the USA, such as a student on a visa, or others here on any other status, would be forced to leave and the federal agencies would go full force on finding any illegals and dealing with them accordingly. This would be a last resort however. I hate to say it, but what we saw on 9/11/01 was what happens when someone is willing to give their life or their freedom for a cause. We as a society have a great place to live and we fight hard for our freedoms. The unfortunate thing is that we aren't as safe as we think. But we are safer than most of the other countries in the world.
