Amidst the images of burning vehicles and riots in Ferguson, Missouri, the US President, Barack Obama, has responded to growing concerns about policing by pledging to spend $75 million to equip his nation’s police with 50,000 Body Worn Videos. His initiative will give added impetus to an international movement to make street policing more transparent and accountable. But is this just another example of a political and technical quick fix or a sign of a different relationship between the police and science?
At the heart of the shift to Body Worn Video is a remarkable story of a Police Chief who undertook an experiment as part of his Cambridge University Masters programme. Rialto Police Department, California serves a city of 100,000 and has just over one hundred sworn officers. Like many other departments, it had faced allegations that its officers used excessive force. Its Chief, Tony Farrar, decided to test whether issuing his officers with Body Worn Video would reduce use of force and complaints against his officers. Instead of the normal police approach to issuing equipment like this, Farrar, working with his Cambridge academic supervisor, Dr Barak Ariel, designed a randomised field trial, dividing his staff’s tours of duty into control – no video – and treatment – with video. The results showed a significant reduction in both use of force and citizen complaints.
Why is this story so different? A former Victoria Police Commissioner described the relationship between the police and research as a “dialogue of the deaf”. The Police did not value research and researchers frequently did not value policing. Police Chiefs often saw research as yet another form of criticism of the organisation. Yet, despite this, research has had a major effect on modern policing. There are very few police departments in the developed world that don’t claim to target “hot-spots” of crime, an approach developed by a series of randomised trials.
However, even with the relative success of “hot-spot policing”, police have not owned the science of their own profession. This is why Chief Farrar’s story is so important. Not only was Farrar the sponsor of the research, but he was also part of the research team. His approach has allowed his department to learn by testing. Moreover, because the Rialto trial has been published to both the professional and academic field, its lessons have spread and it is now being replicated not just in the United States but also in the United Kingdom. The UK College of Policing has completed randomised trials of Body Worn Video in Essex Police to test whether the equipment is effective at gathering evidence in domestic violence investigations. The National Institute of Justice in the United States is funding trials in several US cities.
This is the type of approach we have come to expect in medicine to test promising medical treatments. We have not, up to now, seen such a focus on science in policing. Yet there are signs of real transformation, which are being driven by an urgent need to respond to a perfect storm created by a crisis of legitimacy and acute financial pressures. Not only are Chiefs trying to deal with the “Ferguson” factor, but they also have to do so against a backdrop of severe constraint.
“Science can provide a means to transform policing as long as police are prepared to own and adopt the science”
As the case of Body Worn Video has shown, science can provide a means to transform policing as long as police are prepared to own and adopt the science. But for Body Worn Video not to be an isolated case, policing will need to adopt many of the lessons from medicine about how it was transformed from eighteenth century barber surgeons to a modern science-based profession. This means policing needs an education and training system that does not just teach new recruits law and procedure, but also the most effective ways to apply them and why they work. It means that police leaders will need to target their resources using the best available science, test new practices, and track their impact. It will require emerging professional bodies like the College of Policing to work towards a new profession in policing, in which practice is accredited and expertise is valued and rewarded.
Obama’s commitment to Body Worn Video will not, of itself, solve the problems that Ferguson has so dramatically illustrated. The Rialto study suggests it may help – a bit. However, the White House announcement also included money for police education. If that is used wisely and police leaders grasp the opportunity to invest in a new science-based profession, then the future may be brighter.
