Sicario (2015)

Visible crew/equipment: Towards the beginning of the film we see the convoy driving to Ciudad Juárez on the highway. In the reflection of the last car one can see the Russian Arm used to film the vehicles.

Title Card: The word Sicario comes from the zealots of Jerusalem, killers who hunted the Romans who invaded their homeland. In Mexico, Sicario means hitman.

Trivia: Originally, Alejandro was meant to have much more dialogue, and his tragic origin would have been revealed earlier in the film. Actor Benicio Del Toro and director Denis Villeneuve ended up agreeing that the character worked better as a silent, mysterious type and that the revelation of his origin should occur late in the film. It is estimated that as much as 90% of his dialogue was deleted during rewrites.

Question: A major scene and gunfight take place right after the convoy crosses the border and is forced to stop in traffic. The members of the convoy scan the surrounding vehicles and find two filled with men carrying weapons in full view, not to mention the occupants looking like stereotypical gang members. How did those two cars cross the border in order to be in the same slow traffic - surely border control would have stepped in? How did they come to be there for the attempted ambush?
