No problem. Not only do they sneak across the border at will, but they also shoot at Americans from the Mexican side of the border. Nothing to worry about here, keep moving along. The border with Mexico is completely safe for Americans.

Wonderful. Illegal immigrants might be responsible for burning down 500,000 acres of Arizona pines. But the border is safe. Remember Obama, Napolitano, and Holder have all said the border is as safe as it ever was. Only it was never safe! People in Arizona that live next to the border seem to have a different opinion!
