And those organisations are?

I can see it now:
Paedo: “Hi, I know this child’s social security number, bank account and am calling myself Jim – which is his Dad’s name”

little boy: “Who the hell are you? Bugger off you weirdo”

Paedo: “Timmy, it’s me, your Dad, don’t you recognise me. Didn’t I have the right benefits code?”

little boy: “I’m John. I don’t know my child benefit number. The CD’s didn’t have photos of all the children on. No go away before I kick you in the goolies.”

Paedo, later, at home on phone: “hello, Barclays Bank? I’ve got the social security number of my three darling daughters here and their bank details… could you send me naked photos of them for me to wank over please…. hello… hello, are you there..?”

Like I said, scaremongering. It’s called Moral Panic and the theft of the CD’s is enough. Don’t add the eponymous bogeyman in as well. You’ll be suggesting illegal immigrants and Irish travellers are working together to use the CDs next…

Scaremongering Ellee, pure scaremongering.

What’s a paedo going to do – masturbate over social security code numbers?

If you want to find a kid to fiddle with, I’m pretty sure there are easier ways than tracking down two CDs which have gone astray between Government departments, don’t you? There’s things call “schools” and “nurseries” and “playgrounds” which, so I’ve heard, have loads of the blighters playing in (children, not paedophiles… but you never know.)

The personal details of 15.5 million kids would be useful for fraudsters who can use it to start qualifying the ‘big’ (i.e. rich and gullible) targets from it for future use.

Could be xmas has come early for some.
