But why did they come up with such an objection? They needed something to latch on to, and i think they found it in the "that looks to good to be true" thing.
When you take a picture and spread it across the international media, it gets seen by all sorts. Some of those sorts include fans of wolf photography, whether wild or captive. If the wolf is distinctive, that drastically raises the odds of recognition.
I've only seen one of the comparison pictures, and have to admit to being unfamiliar with how distinct wolf faces are.
