Tony Blair's Keith Joseph Moment?

Politaholic is a little worse for wear having just been to the pub on the way back from work. But unless I am hallucinating I have just heard Channel 5 News say that Tony Blair has just made a speech in which he said that potential troublemaklers (criminals, etc) can be detected before they are born (lock 'em up that's what I say). It doesn't surprise me at all that a public schoolboy thinks like this, but dear Jesus he is the Leader of the Labour Party. When Keith Joseph said something not entirely dissimilar years ago it ended his prospect of leading the Conservative Party. But the Labour Leader? - dear God, I need another drink.
