Build an electric fence and mine it, just like the Berlin wall, this has to stop, who knows who is sneaking in ?
As I said earlier, this presents a clear and present danger to the security of the Unites States, take politics out of this, stop looking for votes from certain racial groups and do something to protect EVERY American/resident Alien.
Automate the Agriculture business too, that wil wipe out a vast majority of undocumented workers, this has to stop guys, I mean, how can anyone know who and WHAT is being brought over the border?
