Dittrich: "...what a challenge it really is to seal off this stretch of 1,900 miles, especially when there's - you know, there is just this kind of endless pressure pushing people north.
It's kind of a consummately rational decision to cross the border, like it or not, because as soon as they do, their earning potential increases six-fold. If you happen to bring, you know, some cocaine with you, its value doubles as soon as you cross the line. I mean, there are just these pressures. So it's a remarkable sort of feat that we are attempting at this point to seal off that, you know, vast and largely empty stretch."
