That is unfortunately what it became. The original intention was to advise LEO's that the driver was also a LEO and may be armed and/or could provide assistance in an emergency.
If there was no other LEO's around I would provide assistance to an LEO in an emergency! I don't put any bumper stickers at all on my car though although the idea of not getting speeding tickets sounds nice! I used to speed a lot when I first got my car but I've tamed my tendency to do so now. I feel like I've seen a car with a ProShooter logo on it, do you drive an SUV? I could be thinking of something else.
In my friends neighborhood there's a lot of people that drive old "surplus" (for lack of a better word) Police Interceptor Crown Vics and dark Impalas thinking they won't get pulled over driving them, but it seems I see them pulled over more than any other type of cars hahaha.
I have never wanted vanity plates because for some reason I'm paranoid and feel like my random plates would be harder to remember, but would however be interested in the Don't Tread On Me vanity plates, I looked on the DMV site and didn't see them I'll have to check that out I would probably get something random on them though.
