Don't need an image search. Much easier and simpler to just get a license plate number (easy enough for provider or anyone in the vicinity) and you can find out everything about him (or anyone, for a nominal monthly fee). Everything he's ever done, addresses, wives, kids, businesses, where he works, etc. Perfect for both LE and anyone up to no good.
Next time be on the alert for the suspicious guy sitting in a car writing something down as he watches guys go into and come out of AMPs (with a bottle of water and a smile on their faces, usually). As David Crosby said, "it increases my paranoia, like looking in my mirror and seeing a PO-lice car." (If he's taking photos, he's probably a private detective hired by your wife.)
Geez, Treetop, you really like stoking paranoia, don't you?
