Machine-Learnt Bias? Algorithmic Decision Making and Access to Criminal Justice

The pressure on the criminal justice system in England and Wales is mounting. Recent figures reveal that despite a rise in recorded crime, the number of defendants in court proceedings has been the lowest in 50 years. This indicates a crisis of access to criminal justice. Predictive policing and risk assessment programmes based on algorithmic decision making (ADM) offer a prospect of increasing efficiency of law enforcement, eliminating delays and cutting the costs. These technologies are already used in the UK for crime-mapping and facilitating decisions regarding prosecution of arrested individuals. In the US their deployment is much wider, covering also sentencing and parole applications.
