Yeah you'd do that but if we tried that here in the US, you and the rest of the world would scream bloody murder about how unfairly the US treats illegal immigrants. Look how the world is responding to the US building a fence to protect OUR borders. Every country in south america is *****ing about it. Saying it's unfair that we would even consider keeping the poor and oppressed people of south america from entering our country. It's all a bunch of BS, because we're damned if we do and damned if we don't. I personaly feel that the fact that the president of Mexico went on world wide TV and said he would do everything in his power to prevent a fence from being built on OUR side of the border is a hostile act and should be treated as such.
I think instead of spending the money on a fence that money should be paid to volunters to patrol the boarder and have permission to shoot on sight anyone attempting to cross the border anywhere other than a designated border entry station. Any armed response from the south side of the border should be responded too with maximum force by the US Military and be considered an act of war against the US.
The rest of the world doesn't like it, too damn bad.
