And you know this how...? You can believe that 50,000,000 more than the ENTIRE population of Mexico and Central America are going to wonder up to the United States, but I don't.
I heard on a news documentary I saw, that there are about 6,000 illegals coming across the border a night. It was actually a documentary on the border towns in Mexico and how rampant they are with crime/drug lords/you name it.
Now, how accurate the numbers are, I don't know, this is the "news" were talking about. And whether this accounts for the "day time" numbers as well, the story did not say. But still, if there numbers are any where close, you gotta figure 6,000 a day x 365 days = 133225, over how many years?
