"Keep your right hand in the air. Use your left hand to take the keys out of the ignition. Drop the keys on the ground outside your window."
I did have to go to the MVD, but the stop was the worst of it. https://www.amazon.com/License-Plate-Frame-Security-Screws/dp/B017ADQBZC I bought security bolts like those. I recommend them. It's petty hard to remove them without the tool. I debated spot welding the thing on-which would require grinding the wild to remove. Ultimately, u decided the bolts were enough. While I was at it, I bought a shield for the catalytic converter.
I think a dummy plate would be problematic for me because I would forget it and be driving with it on. If you had asked me right after the stop happened, though, I would have been on board.
