Just this morning, the local news (Phoenix News 3) chopper had live footage of what must have been these guys in action. They identified them as O’odham Swat police. DPS and Customs Narcotics were also involved. Also a Blackhawk chopper.
When they got to the Suburban they were after, they signaled that the smugglers had fled. They gave the location as Stanfield, AZ. I will be looking updates.
