I stand corrected, you're numbers are probably closer to the truth. The sad fact of the matter however is that we have no real idea how many have come across, due to our OPEN BORDERS!
Not your fault...that's what the article said!
The BP in Washington admits that 1 or 2 cross undetected for each illegal caught. BP agents at the border say the number is actually between 5 and 10.
And you know, that doesn't even begin to count those who simply overstay their visas. We ought to put Blockbuster in charge of visa control, whaddya think? Overstay more than 2 days, and Whammo! you're busted.
