re: I must clarify with an addition.
Mary Anne, if you read my original post above, you can tell that I'm not in favor of shooting anyone that crosses any border. I should have added to my answer on my second response that. Yes, the U.S. should have always protected it's borders, everyone can agree on that one! The problem lies with Mexico's educational and economic system. I agree with Lee with his point on Mexico's relunctance to stop them from crossing their side of the border.
I agree with what Bush has proposed seems that you agree as well.
The problem is with the Mexican government and if you want to stretch it farther, with Cuba's government as well a place that has been known to kill those that are returned regardless of their reason for leaving.
