In 2024, more than two million crimes went unsolved in England and Wales, with police unable to identify a suspect. That figure has increased by 180,000 since 2022, despite there being 86,000 fewer crimes in the same period.

So with detection rates down, and constant financial pressures on the police services across the UK, should crime prevention play a greater role in policing? Targeting preventable crimes and the people most likely to commit them, a process called "focused deterrence" is being trialled at five sites in England. Police services already have better intelligence resources available than in any time in history, and they are also working with care services and other agencies to flag up potential problems.

How could crime prevention be taken further? Would a more academic approach to policing result in knowledge being spread more quickly, and how could police be better prepared for emerging crimes as society and technology change?

Ultimately, could it lead to lower crime rates and financial savings, and is there any evidence to suggest it does either?
