Sorry that it took me so long to find the Nat Geo article - "Mexico's Other Border". It appeared in the February 2008 magazine.

It's pretty lengthy. Unfortunately the website article doesn't seem to have the numerous photos that were in the magazine. None the less it gives an excellent insight into the inner workings and corruption that is fueling the mass migration. It does confirm that an Italian Priest is running some safe houses. I recall a Vatican connection also but haven't as yet spotted it here. But it exists. It said "Vatican" not Pope as I recall.
I haven't actually made a connection with the current Pope, as yet. But he is Latino, Agentinian, and a flaming liberal. Whatever is going on may be deep under the covers there. But note too that Catholic Relief Services is up to their arm pits presently in Texas with these children that are coming across.
Anyone who reads the article will see also the blatant Government sanctioned action of Grupo Beta.
It's almost all about money. Everyone getting a piece of the action.
