My Lords, I thank the noble Lord for his broad support and support in principle for what we are seeking to do here. I also
listen with great care whenever he talks about history and literature. Today he combined both. I am forever learning from the noble Lord.
On the specific question of why six months, it is our view that there must be a limit otherwise people who have been arrested and then had proceedings against them dropped for lack of evidence would never actually know whether they were free of the risk of having their DNA and fingerprints taken. Six months has been regarded as the reasonable limit in legislation passed by this Government as well as the previous one. The noble Lord mentioned the Protection of Freedoms Act, namely that the DNA of a person who has not committed any offence should not be retained indefinitely. He used that as a premise for saying perhaps that the Government are U-turning. This is not a U-turn. I always regard these things as progression and I think we have moved in the right way and I am glad that the noble Lord respects that. I beg to move.
