Why do you think cracking down on illegal immigrants would help prevent terrorism? If my memory serves me correctly, none of the September 11 hijackers were illegal immigrants. And I don't think that foreigners are significantly more likely to kill than home-bred Americans are. Timothy McVeigh was not an illegal immigrant. Ted Kaczynski was not an illegal immigrant. Eric Robert Rudolph was not an illegal immigrant. The way to stop terrorism isn't to deny foreigners rights that we let ourselves have. If everybody had the freedom to live where they want and to live the kind of life that they want to, terrorism wouldn't even be an issue. Freedom and love, not repression and hate, are the solution. As Benjamin Franklin so wisely said, "Those who would give up Essential Liberty to purchase a little Temporary Safety, deserve neither Liberty nor Safety."
