How do we know there has been no repeat crime?
The criminal is flexible. Such a person is not exactly likely to be operating within the cream of society. He may have committed different types of crime since then, perhaps in another place, and no -one will have connected the dots.
But we are being told to fear a man who enters our homes and steals our children. That is what both you and Sadie have said in this thread!
Sadie "Do you want this gawd awful guy stealing more kids? Surely not"
Sherlock "This is a point that is not made often enough.
Any abductor is likely to be roaming the streets at the moment - unless he has been incarcerated for another crime in the mean time - and is a potential threat to other families."
You're both using emotive language, conjuring up images of men hiding in wardrobes, waiting to pounce on our children.
I think that a point worth making is:
There has been no repeat crime with the same M.O.
There is no evidence that "this gawd awful guy" has
ever offended again. In fact there is no evidence that he ever existed at all!
