Crime and Security Bill

I accept that there is not a great wealth of research in this area, but it will grow in all parts of the world. The latest research we have is being independently peer-reviewed as we speak. It suggests that the Jill Dando Institute research on which we based our original proposals—which showed a difference in the hazard curve, or the propensity to be re-arrested, between those arrested but not convicted for serious offences and those arrested but not convicted for less serious offences—is wrong. In fact, the Jill Dando Institute itself said—unfortunately, nine months after it produced the research—that it was flawed. The latest research shows that there is absolutely no difference between the two, which is a very important factor. As to the Scottish scheme, I shall come on to that in a few moments. Let me return to what I was saying about human rights considerations. This House is, of course, aware of the judgment handed down by the European Court of Human Rights on 8 December 2008, which ruled that although holding DNA records of those who had no conviction could well be proportionate in some cases, it was unlawful to hold those records indefinitely. This Bill responds to that judgment. Secondly, we must consider what the most recent evidence in this developing field of research tells us. The research we published, along with our proposals in November 2009, shows that there is a link between previous arrests and future arrests. It also shows that, as time passes, that link diminishes so that after six years—not two, three or four, but six—the probability of re-arrest is no higher than for the rest of the population. Thirdly, we must consider concerns about privacy. Many people find the idea of someone retaining their genetic material disturbing, which is why, although not required to do so by the European Court judgment, this Bill will require all DNA samples—namely, the actual genetic material—to be destroyed after six months. What is retained by the database is the unique 20-digit code that forms the DNA profile. Fourthly, we must be mindful of the public's very reasonable expectation that the police will harness this enormous scientific advance to protect them from the most horrific crimes, and ensure justice for victims and their families. Under the framework proposed by the Bill, the DNA profiles of all those convicted of crimes, and all juveniles convicted of serious offences, will be held indefinitely, and the police will be given the powers to take DNA samples from people who were convicted of serious violent and sexual offences in the past, before DNA was routinely taken, and from those who have committed such offences and are returning from overseas. The DNA profiles of those who are arrested but not convicted will be retained for six years, in line with the findings of the best available research. I will talk more about that soon. There is one important exception to the six-year rule. As national security investigations, including counter-terrorism cases, can go on for many years, setting a six-year time frame would potentially be damaging in these circumstances. We therefore propose to allow the retention of DNA profiles beyond the six-year point in these exceptional cases, which have been known to be live for as long as 25 years. Under the framework set out in the Bill, the records of under-18s convicted of serious crimes will be held indefinitely. However, for those convicted of minor offences, if it is a first conviction, the record will be kept for five years, and only if it is a second conviction will that record be held indefinitely. We make this distinction because it is right that the criminal justice system distinguish between adults and children. For under-18s who are arrested for, but not convicted of, both serious crimes and minor offences, their records will be retained for three years. The records of 16 to 17-year-olds—those entering the peak offending years—will, however, be retained for six years where they have been arrested for, but not convicted of, a serious offence.
