Reichert stops them and, after making a computer check from his patrol car, asks Huff about a previous arrest for marijuana possession. Huff, 50, admits he was once arrested but never convicted. “It was thrown out,” he says.

After some conversation about drugs, in which Reichert observes that Seaton seems nervous, the officer asks to search the vehicle.

“There are no drugs in the car,” Huff says. “I would just like to go on my way if I could.”

Reichert separately tells Seaton, “We have a major problem ... with people running guns and drugs and other illegal stuff up and down the highway. I’m not overly concerned about a little bit of a personal amount of marijuana. We’re looking for big drug traffickers and people that are running loads of dope.”

Interstate 55-70 is a heavily patrolled, known drug corridor. In Illinois, police departments can keep a portion of drug money they seize.

The video shows Reichert walking around the car with a dog that does not appear to sense anything. They go again, and Reichert is heard saying: “Show me where it’s at. Show me where it’s at.” They’re out of the camera’s view when the dog barks.
