Cardboard you still haven't addressed my suggestion yet you, like Greg, incorrectly complain that no alternatives are presented.
You also make ridiculous claims like, "A wall or fence or whatever you want to call it, electronic surveillance combined with patrol and laws indicating that anyone who trespasses can never return to the U.S. is the solution."
We're talking about illegal immigration and you are suggesting laws saying they cant come here! Do you hear yourself?
