Police are gathering the personal details of thousands of activists who attend political meetings and protests, and storing their data on a network of nationwide intelligence databases. The hidden apparatus has been constructed to monitor domestic extremists". Detailed information about the political activities of campaigners is being stored on a number of overlapping IT systems, even if they have not committed a crime. Senior officers say domestic extremism, a term coined by police that has no legal basis, can include activists suspected of minor public order offences such as peaceful direct action and civil disobedience. Three national police units responsible for combating domestic extremism are run by the "terrorism and allied matters" committee of the Association of Chief Police Officers (Acpo). In total, it receives 9m in public funding, from police forces and the Home Office, and employs a staff of 100. The main unit, the National Public Order Intelligence Unit (NPOIU), runs a central database which lists thousands of so-called domestic extremists. It filters intelligence supplied by police forces across England and Wales, which routinely deploy surveillance teams at protests, rallies and public meetings. Vehicles associated with protesters are being tracked via a nationwide system of automatic number plate recognition (ANPR) cameras. Police surveillance units, known as Forward Intelligence Teams (FIT) and Evidence Gatherers, record footage and take photographs of campaigners as they enter and leave openly advertised public meetings. Surveillance officers are provided with "spotter cards" used to identify the faces of target individuals who police believe are at risk of becoming involved in domestic extremism. Targets include high-profile activists regularly seen taking part in protests.
