“We are supposed to believe that someone with tens of thousands of dollars worth of guns and ammunition is expecting to get past the Mexican border guards/bribe collectors but is careless enough to get stopped for a traffic violation and then act guilty of smuggling?”
First, when you cross the border headed south, there are no “exit checks” on the US side. You leave the USA without ANY contact with US customs or border patrol. The first checkpoint you hit is Mexican. A “random” machine hits the red or green light. If you get green,,,you drive straight in and never hit another check.
As for a red light,,, those guys arent that good, or well paid. But they are bright enough to know they’ll be dead by the end of the week if the screw with a southbound load.
OTOH,,Texas DPS and other agencies are very good at finding smugglers. This was a Southbound Cartel load, driven by illegals.
We used to get pass the border (green/red) light stop without a lot of problems...But that was a lonnnnngggg time ago...
Now, before all the unrest started, a big Ford truck with Texas license plates would get the “extra special” treatment way into the interior at the 26 kilometer checkpoint on the road from Laredo and Sabinas-Hildalgo...
I have a brother-in-law who is a Mexican Federale, and we used to show the inspector(s) his card and that usually got us a pass...Nowadays we don’t even bother to go anymore...Not with all the shinanigans going on in that country...
