Definitely what
@antipodean says. My looking into this particular area is very superficial, and it's more about considering the image manipulation side. This is a picture of Geoff Campbell and Matt, is it real, or is it a paste up?
That picture reminds me of George and Zippy, they only have a single arm too.
In my view
it's a paste-up. So why did it need to be a paste-up? If Geoff Campbell checks out as being real, as he apparently does, we should instead investigate how far Matt Campbell's existence goes back, because I think that is the same person photographed twice. But if the UK Government is involved, they gave themselves the power to create identities including birth certificates and send them back in time so they appear to be genuine. They used the
Mary Bell "murders" as justification, and strengthened it with the
James Bulger "abduction and murder". Both involving child murderers that were apparently given new identities on leaving prison.
Just on the James/Jamie Bulger case, I realise I appear obsessed with this idea, but I think Jon Venables and Robert Thompson are pictures of the same boy (actually probably a girl) presented to us differently. Because none of what the British Establishment do is without reason; and I think part of this "crime" was to get data on how people perceived the two boys by their mugshots. And the general view was people could believe the murder of Robert, but less so of Jon.
