Telegraph reports that civil liberties campaigners accused the Government last night of compiling a national DNA database "by stealth" as police prepared to enter the two millionth profile into the system. Police powers to keep DNA samples have been strengthened considerably since 2001 when they were first allowed to keep the information indefinitely from suspects who were not convicted.

The new Criminal Justice Bill now before Parliament extends this rule to people who are arrested but never charged. David Blunkett, the Home Secretary, said the importance of DNA profiling to criminal detection outweighed the civil liberties objections.

The DNA and fingerprint databases have become vital weapons in law enforcement, making our communities safer by helping to put thousands of repeat criminals behind bars.

That would be fine, no one disputes the usefulness of advanced technology in crime detection. The problem is, as Gareth Crossman, a spokesman for Liberty, points out:

The Government is hell-bent on creating a national DNA database by stealth. It claims that only criminals will be listed, yet is passing legislation so DNA samples will be retained indefinitely for anyone who is ever arrested, whether guilty or innocent.

If you have any doubt about the government's intention - the new Health Secretary, John Reid, plans to ask the genetics watchdog to consider the case for DNA screening of every newborn baby. All in the best possible taste, of course...
