No link as I just heard it on the news, but apparently a large Mexican news organization is pushing for a wall on the border. Their Southern border that is. :)
They want to (rightly) stop the illegal flow of Central Americans who try to cross Mexico to get to the US, but who never quite make it out of Mexico. A large portion of them are resorting to crime and/or sucking up public resources. Huh. Imagine that.
