Too skool for cool
I think the usual method is to use the identity of a dead child with a relatively common name - if someone turned up with a rare name to the point where it could be recognised their cover would be instantly blown anyway.wtf?
surely this means there's an (admittedly slight) risk that someone they encounter might just be related to the family whose child died.
wouldn't it be far safer to manufacture a complete new identity - i'm sure the powers of the state could manage to forge a few birth certificates...
I'm not that surprised by this - it's in a lot of novels and is doubtless part of spying 101 and the police have never been particularly imaginative.
