Protection of Freedoms Bill (Programme) (No. 3)

The hon. Gentleman highlights a key issue—the retention of the DNA of those convicted of offences, with which I absolutely agree. Some 75% of those who were engaged in the rioting—or, at least, those who were brought before the courts—had committed prior offences. That clearly makes the point that there is a need to put the DNA of those who are guilty of crimes on the database, rather than keeping those who are innocent of any crime on it, which is the approach of the Opposition and was the approach of the previous Government. The Labour party persists in its approach of keeping the DNA and fingerprints of innocent people for many years, no matter what those people have been accused of and no matter how little evidence was ever uncovered in relation to them. It is worth putting these issues into context. Of course, DNA is important. I fully recognise the scientific breakthrough of being able to take DNA to search against the database and, most importantly, to retain crime scene DNA evidence in a cold case database against which matches can be made. However, the collection of DNA is part of a process of investigation and is not a panacea in itself. I think that if the Labour party could have its way, it would continue with the previous approach of simply trying to put more and more data on the database regardless of people's guilt or innocence. However, it is interesting to look at what has been the result of adding many more people on to the database. In 2004-05, 2.8 million people were on the national DNA database and in 2009-10, the figure was 4.8 million people. Now, let us look at the number of detections in those years. In 2004-05 there were 35,605 and in 2009-10 there were 32,552, so when there were 2 million more people on the database, there were 3,000 fewer detections. I therefore challenge the suggestion of the right hon. Member for Kingston upon Hull West and Hessle that the more people's DNA is on the database, the more effective it is. The figures do not necessarily equate in that way, as the historic evidence shows.
