Just like speeding, it goes great until you get caught. You will always hear stories about all those people that do it and never get caught, but you are never the lucky one. Do you feel lucky?
One of my favorite reasons for stopping people that had "my attention" was ones that lacked a front plate (when required) or obstructed plate (visible 200' to the rear). Amazing how many people have another vehicle's plate on their vehicle, stolen vehicle, expired plates, homemade plates and mismatched plates. A simple stop and verify, unless you have that one time for me;
"Hello sir. I pulled you over for that obstructed rear plate. I will need to see your Driver's License, Registration and Proof of Insurance and ask you about that Ski Mask, roll of duct tape and can of Mace on your passenger seat . . . "
Yeah, the most innocent stops provide the most interesting arrests. As long as you don't mind a few minutes with a diligent police officer, go right ahead and forget about that plate.

p.s. Oh, yeah. My SGT., during his monthly ride alongs, would count and record the number of vehicles we encountered without front plates and obstructed plates that I didn't turn and stop. Yeah, a lot of us didn't really like that SGT much either.
