This is a legitimate federal inspection group. We saw them at several locations while we were driving through Sinaloa last year and didn’t get stopped until the last check point just as we were leaving that state. We were initially under the impression from another couple that drove before us that this could possibly be a cartel, but we were assured by locals that this was a government group. And then we looked it up on Google. It seems only one or two of the group had the logo on their clothing, so it was very deceiving that they were legitimate. They are looking for money, car, insurance, and registration, and. firearms, etc. We found them to be very polite to us and they didn’t even check our registration or my wallet for money. However, they did check through everything in our van.
