And they park a patrol car beside the interstate with its lights flashing. Then they wait for drug mules to see the signs and get scared thinking they're going to have to stop up ahead, and take the off ramp to avoid it. They have several cop cars and such on the off ramp just out of sight, which they nab anyone who gets off the ramp claiming they were avoiding the drug checkpoint and then have suspicion to search their vehicle.
That's devious and awesome all at the same time.
