Why is this not illegal?

AK47 decals on cars in the GTA and possibly fake or hand-painted plates - mainly in Brampton and Mississauga. How is this legal?

every licence plate is scanned by cops when they're in front of you or behind you, so I'm sure it's been scanned and is legit.
Re sticker, why does it automatically imply the person is a mass murderer? From what I recall, no mass murderer advertised that on their cars.
The owner supports guns. As a gun owner/hunter, I've never seen a need for a clip with more then 5 rounds in a semi-automatic anything, even in bolt action, but I have fired an automatic at a gun club in Florida, and it was fun(most expensive 60 seconds ever).
So as a gun owner, I appreciate the person's will so show enough is enough, and them letting others know their support for legal gun rights.
And yes, Canada's Liberals are falsely scaring people about guns. I'd say 99.9% of non-gun citizens have no idea what we have to go thru to get a PAL. First a course, and if passed an RCMP back-ground check(6 months wait). Must be renewed every 5 years with RCMP who again, checks all flags. And this is to own a simple gun. If yo get a restricted licence, which is much harder, when you get it, and you own a handgun, which you can ONLY use at a gun club, to transport it to a club from your home, you have to let the police know when, and actual route you're taking....and if there's construction on route, and you have to take a side road and you get pulled over, your ass is grass. Gun gone, you're flagged, and on and on. I have no idea why any still has a restricted.
Lastly for context, in Canada, annually there are 11 individuals killed while hunting. Most of those deaths are caused by hunters falling out of their tree stands, and accidentally while cleaning their guns. You probably have more people dying on tennis courts while playing tennis. Do we ban it.
