So... you purport that someone removed your sticker, a sticker that is for all practical purposes impossible to remove in any sort of reusable state?
False dichotomy. A remaining corner of a sticker is not evidence the remainder was stolen.
If someone could have stolen your whole sticker, you could have stolen someone's corner.
As for your registration being current, that's probably a lie, too.
You know you're a notorious (and small childlike liar), right...?
Or, maybe your lies offended the cop. Or, maybe it was your record of traffic citations combined with your unabashed lying:
