fuck it... just close the US/Mexico border then errect a 50ft wall (deep enough so you cant tunnel under) and setup motion sensing machine guns. if you really must travel between, there are planes as well as boats. we might as well set up a mile long razorwire covered fence in the ocean on the sides of the wall. as for deporting illegal aliens to Mexico, we catipult them over the wall... so they are shot on the way over by the automated machine guns. problem solved. :)
