Watch the video. What the officer does is absolutely wrong. He shows complete disregard for the truth and the Constitution. He should be fired.
If you find yourself in a similar situation, do what the driver did. Be respectful. Ask if you are free to leave. And, when the officer asks to search, tell him, “no.” The officer might still search – just like Officer Reichart did – but you’ll have great material to share with your lawyer.
