LORD Justice Sedley has probably caused more than a stir with his suggestion that everyone, including visitors to the UK, should be added to the DNA database (Echo, Sept 6).

I can hear critics of ID cards loud and clear - their belief that ID cards are an infringement of civil liberties will resound in the debate on DNA testing.

There is strong evidence to support the use of DNA. Indeed, many crimes have been investigated successfully, including those from several decades ago before DNA was heard of.

Surely by extending the database we can be assured of opportunities to bring to justice those who inflict terror and misery?

With the war on terror and violence on our streets still a constant threat, there has to be a balance whereby crime can be detected with reference to reliable intelligence and a co-operating public.

But a more informed database must be tempered by good sense and application.

As one leading senior police officer commented recently, DNA records need to be reviewed and decisions made as to whether they are retained or not, together with some guidance on timescales.

After all, most people do comply with the law.
