A “citizens’ inquiry” instigated by the Human Genetics Commission, a government advisory body, wants the records of people who have not been convicted, or whose convictions are long spent, to be deleted from the forensic National DNA Database and says the whole archive should be overseen by an independent body.

The database was established in 1995 in Britain - the country where scientists first pioneered the technique of DNA fingerprinting.

It now contains genetic profiles on more than 4 million people, representing the highest proportion of any population on a forensic DNA database in the world, at over 6 percent.

A future government might misuse the information, members of the inquiry fear. One  says keeping all the DNA records would be the first step towards a totalitarian state.

Police, though, find the database a boon, especially in trying to solve ”cold” cases from the past.

What do you think? Is the database becoming too big?

Under the first, Children’s Secretary Ed Balls proposes that trouble-makers as young as 10 should sign a good behaviour contract . The “most challenging” among them will have to stick to the order or risk a criminal record.

The second, more extreme, suggestion comes from Gary Pugh, forensic science director for the Metropolitan Police, who was quoted in The Observer as saying trouble makers as young as five should be recorded on the national DNA database because future offenders can be picked out an early age.

The idea has been widely criticised, both by those who dislike the idea of stigmatising children at such a young age and those who bemoan what they call the government’s obsession with compiling databases — and its embarrassing tendency to lose personal data. The government has been non-committal but says it is listening to all views.

Do you believe law enforcement authorities need more tools at their disposal to deal with unruly children?
