Regardless of Smithman's attire, the child seen being carried was, according to the Smiths, wearing a long sleeved top and ankle length trousers so she wasn't Madeleine. Madeleine was reportedly wearing short-sleeved pyjamas which had cropped trousers when she disappeared.I agree but it’s the points around formal, jacket and blazer that make the sighting consistent with CB. The hair is also consistent, given the Malaga footage, but not as noteworthy as the jacket.
I do think that a suit jacket is an unusual item of clothing to be worn at 10:00pm on a Thursday night in a tourist town in the Algarve. This doesn’t mean Smithman was CB but it certainly increases the chances it could’ve been.
