Video of an Idaho State Police traffic stop obtained by The Spokesman-Review under the Idaho Public Records Law shows an ISP trooper pulling behind a pickup truck with Colorado plates as soon as he sees it, following it into the “Welcome to Idaho” rest stop, then badgering the 69-year-old driver to allow a search for drugs. The hard-rock radio station that the trooper was listening to provides a soundtrack, interspersed with commercials; when the trooper first sees Darien Roseen’s truck, the radio is blaring the Scorpions’ “No One Like You.”

“Why’d you pull in here so rapidly?” trooper Justin Klitch asks Roseen in the January 25, 2013 dash-cam video. “Uh, I had to go to the bathroom,” Roseen responds. “You didn’t have to go to the bathroom before you saw me,” the officer says, to which Roseen responds, “That’s true - No, I did have to.” “I’m telling you, you pulled in here to avoid me, that’s exactly what you did,” the trooper says. “I mean, you almost hit the curb, you almost ran off the road. You definitely didn’t want me around you for some reason. … Why are your eyes glassy today?”

The traffic stop led to hours of detainment and a fruitless search of the truck that yielded nothing illegal; Roseen has filed a federal lawsuit over it, alleging he was profiled and illegally searched because of his license plate – which was from Colorado. He also has a Washington state driver’s license. Both Washington and Colorado have legalized marijuana; Idaho hasn’t.

The ISP said in a statement last week that it is conducting an internal investigation into the allegations in the lawsuit. “We would like to assure the citizens of Idaho and the visitors to our state that the Idaho State Police holds all of its employees to a high standard which includes following the Constitution of the United States and the laws and constitution of the State of Idaho,” the agency said.
