Guilty of future criminality
Officers are targeting children as young as 10 with the aim of placing their DNA profiles on the national database to improve their chances of solving crimes, it is claimed.
The alleged practice is also described as part of a "long-term crime prevention strategy" to dissuade youths from committing offences in the future.
A Metropolitan Police officer made the claims after figures were released showing that 386 under-18s had their DNA taken and stored by police last year in Camden, north London.
The officer said: "Have we got targets for young people who have not been arrested yet? The answer is yes. But we are not just waiting outside schools to pick them up, we are acting on intelligence.
"It is part of a long-term crime prevention strategy. If you know you have had your DNA taken and it is on a database then you will think twice about committing burglary for a living.
"We are often told that we have just one chance to get that DNA sample and if we miss it then that might mean a rape or a murder goes unsolved in the future."
I seem to remember measuring the shapes of noses had a similar rationale.
