Again, I go back to the Maxine Waters/crack legend. The MMK side must do absolutely everything it can to maintain the fiction that herds of Mexicans are trampling across our borders. To say 'captures' are down during their stint in the desert means they need an excuse to keep the troops' moral up. I think your story about the Mexican army will do just that.
You keep using the acronym MMK. What is MMK an acronym for?
