F&F had nothing in place to track the guns once they crossed the border. Perhaps I've missed some new information, but it is my understanding that not only weren't Mexican authorities informed, our own BATFE agents in Mexico weren't informed. The intent of F&F apparently didn't involve "tracking" the guns at all. The intent was specifically to allow them to enter Mexico and to be used in crimes and recovered at the crime scenes (or afterward), at which point they could be "traced" (not "tracked") back to the U.S. and to gun shops in Arizona.
Thereby "proving" the administration's (and the Mexican government's) dubious claim that the cartels were arming themselves through gun shops in the U.S.
