It is the federal government's job, as outlined in the Constitution, to protect American citizens from foreign invaders.
True. On the other hand, I do not live in a major city and most people would say I was fairly well equipped and trained to take care of myself and anyone with me, wherever I am unless I flew to get there.
I wonder how many people who were murdered in the Twin Towers thought that?

I wonder if you would change your tune if your daughter was raped and murdered and then the Mexican perp fled over the border never to be seen or heard from again?
Where I am located, we worry more about criminal drug gang overflow from Memphis, 86 miles away. It is a real immediate, day to day problem. I thought the 9/11 terrorist came in on Pan Am or other major carrier. If my 43 year old daughter has that problem, the perp will not be heading for the boarder, he'll be heading to Memphis.
