Well, the people with the issue have issues of their own I think. Seriously, it's shot at distance, and you cannot possibly identify faces.

As for legitimacy - perfectly legal. It's shot in a public place. End of.

EDIT - Mod Note - BYTHRIC - The reason your post didn't appear instantly was because, as it was your first post and contained an external link, it was held in a mod queue for approval. I ok'd it as soon as I found it.
