I taped the show and am watching now. What they are uncovering is essentially an ATF cover-up that goes back to 2009, with the fake gun registrations and ATF e-mails that correspond about covering up. There were a couple of massacres in the Sinaloa ares, focusing on a mother of 2 sons, 18 and 20, both of whom were dead in the massacre. There were direct connections from Arizona and Texas that are definitively traced back to the ATF selling large quantities of guns that were used in these massacres. They have fingered the leaders, some of whom are under arrest now and admitted they had help from north of the border.
There is an American guy named Crumpler, who appears to have been a patsy for the government. Crumpler was recruited in Orlando to sell guns at gun shows and apparently grew suspicious as the same buyers were showing up at show after show and buying large quantities. He has evidence that the ATF knew these guys were running guns to Central America and Puerto Rico and these were used in lots of crimes.
Univision has records, witnesses, info from ATF that is very decisive. I am a little more than half through it. I will provide more input when done going over the tape.
Thank you!
