SpuriousLogic writes: Only one crime was solved by each 1,000 CCTV cameras in London last year, a report into the city's surveillance network has claimed. The internal police report found the million-plus cameras in London rarely help catch criminals. In one month CCTV helped capture just eight out of 269 suspected robbers. David Davis MP, the former shadow home secretary, said: "It should provoke a long overdue rethink on where the crime prevention budget is being spent." He added: "CCTV leads to massive expense and minimum effectiveness. "It creates a huge intrusion on privacy, yet provides little or no improvement in security. "The Metropolitan Police has been extraordinarily slow to act to deal with the ineffectiveness of CCTV."
