I honestly thought the pictures were taken by HS from his personal collection- the same way the FBI takes photos and mob journalists feature them
In books staying "taken from FBI archives" or "photo provides by State task force" etc

But having read on, I realised these pics were NOT taken nor owned by HS. Therefore why would he need to tag or copyright them? The person who originally took the pic is the ONLY one who has the right to complain about people using their pics without permission
