Likely plan to use it, while pulling douce "skillz riding". That way, even if cops get a plate number, it won't lead them to the rider. With car plates, (seen it all the time, (back when I was on the job), are stolen then put on a vehicle to pull an armed robbery, or a drive by shooting etc. As soon as they are out of the area, they pull over, take off the stolen plates, and drive away normally, without fear of getting caught.
Stolen License Plate.
Stolen from Queen and Jarvis or King and Dufferin. It's been reported to the police.
Lookout for plate number 3A1C4
Whoever it was literally tore the plate off and left a corner of it bolted to my bike
