I don’t know that approaching from the passenger side is the best method though. Is that something new?
They have doing that for a while here. Much safer for the LEO. They use your vehicle as a barrier in case another car hits something or goes out of control.
They had a trooper here get hit on the driver's side of the pulled over vehicle a few years back , trooper was hit by a truck , killed instantly. The truck stopped , as part of that investigation , they found a perfect imprint of the officers embroidered shoulder patch in the truck's fender. It was so clear you could read the patch in the dent. Trooper got hit that hard.
