Many readers informed us about the opinion of Lord Justice Sedley, a senior UK Appeal Court judge, who said that everyone in the UK should have their DNA recorded in the national database — including visitors. Reader ChiefGeneralManager writes, "Sedley calls the current database 'indefensible' because it contains a hodge-podge mix of people, including children and those who have been in contact with the police. His view is that we should make it compulsory for all DNA to be recorded to remove this anomaly. The UK Information Commissioner has expressed some concerns, but not dismissed the idea outright." And reader john.wingfield adds, "Just under two weeks ago, the Independent reported that the Government has admitted that an eighth of all records on the DNA database are false, misspelled, or incorrect — over half a million records. This raises the possibility of a breach of the 4th data protection principle of the Data Protection Act 1998: 'Personal data shall be accurate and, where necessary, kept up to date.'"
