Is it the epic historical film from last year?
Do you see a triangular number and a pair of twin primes (149 and 151)?
Or do you recall how Jo Shaw, the Lib Dem PPC for Holburn and St Pancras revealed in the Telegraph last week that that’s how many children are added to the UK’s DNA database each and every day.
Almost 1.1 million youngsters aged between ten and 17 have had their profiles recorded by the police since 2000, with a large proportion aged under 15, the Daily Telegraph can disclose.
And around one in six are likely to have never been convicted of any crime.
Ministers are currently reviewing the database but proposals would still see the profiles of innocent people kept for up to 12 years.
Youngsters who commit one minor crime will be kept on until they reach 18 while those guilty of sex or violent crimes will be kept indefinitely.
Jo Shaw, the Liberal Democrat parliamentary campaigner for Holborn & St Pancras who obtained the figures, said: “Labour’s approach to tackling crime is unfair, heavy-handed and ineffective.
“Storing the DNA of thousands of innocent young people as young as ten is unlikely to solve our crime problems, but is a costly way of stigmatising young people. If you’re innocent, you shouldn’t have your data on who you are kept for years.”
