Anyone who has traveled in Mexico/Baja since late 1960’s, early 1970’s would know you would inevitably run into a military style inspection (inland) from Federale soldiers completely armed and ready to shoot to kill.
I traveled the length of Baja in the late 90s/early 2000s on a number of occasions covering the races and went through the drill and had my truck searched repeatedly. The first lesson there is do whatever you are told. If you do that, odds are its all cool.
Unnerving, but the price you pay.
You f with them, you go bye bye and the Federalie Capt. gets a new truck to drive. Thats reality.
Today, I’d NEVER thing to go there for love nor money.
