I think the impression of the mccanns comes from a mixture of:
what they did in leaving the child (bad parenting and it probably will haunt them for the rest of their lives),
Being perceived to have avoided police charges of neglect when others have been charged (people have viewed it as "if they were poor, they would've been charged"),
Getting a publicist early doors (people viewed it as managing an image).
Unfortunately, we may never know the truth of what happened. Even with this German bloke, there may be no concrete evidence, only that he is a criminal who was in the area at the time.
