Police turn to ‘precogs’ in knife emergency
In the face of the crisis over knife crime, Britain is developing “predictive policing” technology akin to the sci-fi movie Minority Report. The plan is already proving controversial.
West Midlands Police Commissioner David Jamieson yesterday called knife crime a “national emergency”. Home Secretary Sajid Javid declared “young people are being murdered across the country”. He will hold a crisis meeting tomorrow.
Bernard Hogan-Howe, former head of London’s Metropolitan Police, said the violence had three roots: drugs, a culture of knife-carrying and a growing number of “young men who do not seem to care”. He called on the government to appoint a “knife crime tsar”.
But his most radical demand was for behavioural science software that would help police find who and when to search. He was referring to a secretive plan for UK police forces to predict crime before it happens using artificial intelligence.
The idea has been compared to the plot of the Tom Cruise sci-fi classic Minority Report, in which clairvoyant “precogs” predict crimes before they takes place.
In the real-life version, called National Data Analytics Solution (NDAS), the precogs are replaced by huge data banks feeding computer algorithms.
People will have a “risk score” based on gang membership, previous convictions and psychological profiling.
West Midlands Police is testing a model due for UK-wide launch later this year.
But isn’t the real answer young people themselves? Peter Traynor, a British academic who interviewed teenagers involved in knife crime from all over the UK, says that most are looking for ways to fight it. “They just need support.”
And since when did the police decide they could turn from crime fighting to launching a surveillance state? The Alan Turing Institute on digital ethics has seen some of the West Midlands Police project and is deeply alarmed. Quite apart from the potential abuse of data, what if predictive policing predicts wrongly?
- Has the time come for young people to campaign against knife crime?
- “It is important to recognise that many young people do not offend and often find themselves trying to resist and confront those who carry knives”. Do you have a personal experience of knife crime? Please describe it in less than 500 words.

Q & A
- What do we know?
- We know that Home Office numbers show there were 42,957 offences in the 12 months ending in September 2018. Although knife crime is on the increase, it should be seen in context. It is relatively unusual for a violent incident to involve a knife, and rarer still for someone to need hospital treatment.
- What do we not know?
- Amazingly, national data on the number of children and teens killed by knives in any given year is not publicly available.
- Behavioural science
- All the subjects that deal with human behaviour -- such as sociology, anthropology, psychology, and aspects of biology, economics, geography, law, psychiatry, and political science.
- Artificial intelligence.
- An area of computer science that focuses on the creation of intelligent machines that work and react like humans.
- A person who predicts something; a person with extrasensory perception or clairvoyance.
- A set of mathematical instructions or rules that, especially if given to a computer, will help to calculate an answer to a problem.
