Ok, my comment above was slightly a drop in the sky to get attention
of the problem, but look let's concentrate more on something else,
which you seem to have purposely bypassed and snipped out, even though
it was one of the key points...

I think what you're missing here is the concept of a "realistic threat model".

As for your "key point":

Yeah, it *could*. Bruce Schneier calls it a "movie plot threat"....

On the other hand, a *smart* attacker would do one of two things:

1) If you don't care who the owner of license plate "IWRKYHOO" is, you don't
*need* a photo - you can just do whatever you intend to do to that car *while
it's in the parking lot*.  If that's too scary, you just park outside the
exit, follow somebody home, and do the dirty deed in their driveway instead.

2) If you're trying to do a targeted attack, a license plate doesn't really
help you much *anyhow* - if you have enough inside help at the local Motor
Vehicles office that you can ask them "who owns plate IWRKYHOO" and see if
it's somebody interesting, you can find the name of somebody interesting via
other means (note you need to do that *anyhow* in order to tell if they're
interesting or just a janitor).  And at that point, you might as well just ask
the DMV insider what license plate(s) the target, and people in his immediate
family, have registered for them.

And anyhow - if you're worried about a mole that's been there 10 years,
remember that *that* guy doesn't need a photo, because he's been there for a
decade and already *knows* that Jim drives the blue Caravan with the dent on
the left side, and Wendy has that little sports car she bought last year, and...

So - come up with a *realistic* threat model that actually *depends* on
having a photo of a car so you can tell the license plate number, and does
*not* imply already having enough info about the target that you don't need
the photo....
