Some countries are more populous; some have more crime. But in no other country are crime fighters quite so knowledgeable about citizens as in Britain. On January 4th a boastful Home Office detailed the triumphs of the world’s biggest forensic DNA database, which holds samples from more than 5% of the entire population of England and Wales. Recent changes to the rules governing the database mean that it may eventually hold profiles from more than a fifth of all adults.
Once a country starts storing DNA samples from criminals it is hard to resist the urge to expand the collection. When the National DNA Database (NDNAD) was set up, in 1995, samples could only be taken from those charged with "recordable" offences. If a suspect was not tried, or was freed, the sample had to be destroyed and the profile removed from the database.
That law was abandoned in 2001, after two men who had been convicted of murder and rape had their cases overturned on appeal
