Regular readers will know I quite often disagree with with what David Pannick writes in the Times; I also find myself often agreeing with David Aaronovitch who writes in the same paper. Well, this week my reactions are more or less as per usual.

First, David Aaronovitch on a national DNA database. It’s not so much that I agree with him that there should be a comprehensive national DNA database – I don’t. I’m happy with the current messy compromise, under which those arrested by the police are swabbed and their DNA kept, so that slowly but surely, and in highly practical way so far as the police are concerned, the database will grow to cover most criminals and troublemakers, as well as of course some wrongly arrested innocent people, without the need to trouble impeccably-behaved maiden aunts. Where I strongly agree with him, though, is in his criticism of the current intellectual fashion for an ill-though-through “unease” about surveillance, DNA collection and so on. He’s right that Liberty and others who take this view must face up to, and openly admit, the consequences of their argument: that murders, rapes and other crimes will go unsolved, and fewer Kate Sheedys will get the legal resolution they seek.

The one point I depart from him on is his last: I think the Sedley position, that collecting DNA selectively is racist, essentially, so we should collect it from everyone, is daft, to be frank. It’s the kind of thing the Archbishop of Canterbury might have said.

And now David Pannick, whose piece on the balance between freedom of expression, specifically the right to use extreme Islamist websites, and security is in effect a skeleton argument for the intelligentsia default position. I agree with his headline; but I’m not sure I’m entirely happy with everything David Pannick says here.

Yes, the more open, public discussion there is of Islamist terrorist ideas, the better – everyone will see how mad they are. But internet discussions are not open, but cliquey, and their aim is not to defend views publicly but to draw in the vulnerable and brainwash them. I think there is is, arguably, a war of ideas here, as with, say, Nazism in the 1930s, and that freedom of expression may not be the moral trump he implies – indeed, we may even, legally, be dealing with that kind of expression which is outside human rights protection, according to the European Court of Human Rights case of Garaudy v France.

And how is his approach here consistent with any legal restriction on pornography?

Finally, it seems to me this security/freedom dilemma is a policy problem, not solely a legal one – and I worry that Pannick sees it as solely one for lawyers to resolve.
