Mexico Building it's own Southern Border Fence

Watching the replay of the OReilly Factor this morning and saw this news bit about Mexico Building a southern border fence , Looked around online and can't find it anywhere on a Major news site.
But DBKP (Death by 1000 Papercuts)Has a good piece on it , The Hypocrisy of the whole thing is just Mind-Numbing .

We already Know that Mexico treats Immigrants coming into there country as Lower life forms , they are beaten raped and even killed , Hell they sell the Women Even the young girls in to sex slavery !

But no one is saying anything !

I guess it is O.K. for Mexico to Build a Border fence to Keep the Unwanted out and Violate the Human rights of them while they Do it !

But we can't simply build a Fence to help stop the Flow !
