The bigger issue here is the use of drug sniffing dogs as probable cause. These dogs aren't tested for accuracy by any sort of independent auditor, and it is clear that in many cases they are really just being used for fishing expeditions.
In this case the dog theoretically alerted on amphetamines, which are not always illegal since there are numerous prescribable versions of amphetamines. The rest of the "probable cause" wasn't indicative of any crime in particular (traveling to Oklahoma and New Mexico is hardly proof of anything).
OTOH, if you are going to be traficking drugs for a living, don't leave duffel bags in plain sight, and use your turn signal.
They pulled him over for a completely bogus reason. They were going to search him no matter what. Concealment would do nothing since they were already dead set on searching the car.
In cases like those, police are almost always on information obtained from an informant.

It’s not a random stop.
