I believe it.
I heard it several days ago from a Marine caller on a talk show. He said the "children" aren't rugged or clever enough to make it through the un-patrolled areas of Mexico, and their numbers are too large to avoid detection by the brutal Federales.
They are being flown and bused in, and given a free pass by the cooperative Mexican government.
This latest chapter validates the belief that this whole long-term illegal invasion has been a US/Mexican construct.
Well posted!
