A huge U turn sign should be placed every 50 yards from Texas to California border. Hire some of these super terrorists in Iraq and place them at each sign.( machete in hand )
I believe we should have the national guard on the border. All illegal crossings need to end. Any coyotes that are caught, should be subject to a 20 year stay in U. S. prison.
As for the signs and the people you would like to enforce their message, I want to stay away from things that could cast a shadow on what is otherwise a very important task.
