Dr. Dennis Jennings:

I think it was Plato who first speculated that man or woman - let us not be sexist - unobserved would behave badly.

The past 40 years of the Internet have demonstrated conclusive proof that Plato's speculation was correct, that man unobserved will behave badly. That is just a fact of life and we need to put in place the controls, checks, authorisation, identification and authentication of that identity, the limits and the specific queries that are permitted and so on. If there is any looseness in this, then Plato is right. People will find a way of slipping through the cracks and abusing the system. It is much more complex in an online data environment than ever before, but it is not impossible if thought through.
