It depends upon who you ask. I think that Department of Homeland Security estimates that for every border intruder they catch, five make it to the interior where they're home free. So, if they caught 141,792 then 567,168 made it through this portion of the border alone. That's why I don't believe the oft-repeated "fact" that there are 10 million illegals living in the United States. I think that the true number is far higher than that.
No, Spiff, your math is wrong. If they caught 141,792 then that means that 708,960 made it through the Tucson Sector. You confused 1 out of 5 with for ever 1 caught, 5 make it through. Easy mistake. - Spiff
