AOG - //But then the thread was diverted by the mention of a certain Doctor Shipman, so if that particular ABer wanted to use that invalid connection, I merely suggested that if we could have prevented him from becoming a doctor then his crimes would have also been prevented. //
As the 'particular AB'er' - I contest that my connection is invalid.
Had we prevented Harold Shipman from being a doctor, we could jave prefvented his crimes - but you could extrapolate that to any situation, and it is equally meaningless.
'If Hitler had not been born ...' and so on blah blah - it is utterly meaningless.
My point about Doctor Shipman is that he was not a 'child migrant', but he was still a heinous murderer - background and ethnicity are no indications of a criminal personality.
Your OP has been answered, although you seem not to be happy with the responses you have received - or is it just mine that irk you?
