It just takes one bad apple or one incompetent to "leak" the data out of this system. Once it's leaked, it's out there for the entire duration of several million childhoods. And it's an absolute goldmine for paedophile predators. If a million people have access, somewhere between ten and a hundred will themselves be paedophiles, and perhaps ten times that number so venal that they'll sell data to anyone who pays without a second thought.

Criminal records checks? No good, they haven't been caught yet so they don't have records. Catching them after the "big leak" event is too late. So for God's sake and our children's safety, kill this database before a single byte is stored in it!
