Re: Not Good
So, if she had known there was a potentially violent partner she would have turned up with armed police in tow? I don't think so - it simply is not feasible, which is why your wife probably made a wise decision.
However I have a simple scenario that should worry you. You have children at school age. You have bought a house specifically to get into a good school. The Labour Minister for Education decides that good school are good because they have good pupils and "disadvantaged" kids go to poor schools. So he decides to even things up. He says "I have access to you income (tx Tax Department). I going to come up with a scheme where you DONT get into a good school because you are close, you go to the school I assign you to and the assignments will be based on fairness (read: Middle class kids get sent to poor schools)."
This kind of information allows social engineering on a grand scale. Be afraid, very afraid.
