Possible development in Operation Gunwalker
The operation may have a link to a DEA operation that essentially recruited the Sinaloa Cartel as an ally against the other cartels, as part of which DEA turned a blind eye to its drug shipment. I say may have because the court pleading on which the story is based gives details about other cooperation with the cartel, but guesses as to whether the gunrunning was part of this. On the other hand, the Sinaloa Cartel does seem to have wound up with an enormous share of the walked guns.
