Child Database Insecure

This story in The Times makes my blood boil: the state is going to roll out ContactPoint - a database of all the children in the UK - next year. Social workers fear it could be accessed by child abusers. The state assures us it will be secure and only accessed by those who need to. Meanwhile, the details of politicians and celebrities children will be kept off the database:

"The security fears are fuelled further by the admission that information about the children of celebrities and politicians is likely to be excluded from the system."

So we have a secure system that only those who need to will be able to access so why will politicians children be kept off it?
