Why do nearly half of all criminals released from prison or given community sentences go on to commit another crime? The answer lies in a decades-long drift away from rehabilitation that nobody wants to talk about.

The latest Ministry of Justice data shows 48.7% of offenders now reoffend within a year of their sentence. That's not just high; it's a 67% surge from the 29.1% recorded in 1943. We've spent eight decades building a justice system that releases five criminals knowing two will be back.

This isn't about being soft on crime or tough on crime. It's about a system that's forgotten its basic job: stopping people from becoming repeat offenders. In the 1940s, fewer than three in ten criminals struck again. Today, it's pushing one in two.

The pattern tells a story of institutional failure. Post-war Britain, rebuilding from the ground up, somehow managed to rehabilitate seven in ten offenders. Modern Britain, with all its resources and expertise, can barely manage five in ten. We've gone backwards while pretending to move forward.

Politicians love to announce tougher sentences and more prison places. But when half your customers keep coming back, you're not running a justice system. You're running a revolving door. Every press conference about being "tough on crime" rings hollow when the data shows we're creating more repeat offenders than we're preventing.

The human cost is staggering. Each reoffence represents another victim, another family affected, another community made less safe. But there's an economic cost too. Processing the same offenders through courts, probation services, and prisons again and again while new crimes pile up behind them.

What changed? The 1940s system focused on getting people back to work, back into communities, back into normal life. Sentences were shorter but rehabilitation was real. Today's system warehouses people in overcrowded prisons, then releases them with little support and fewer prospects.

The irony is brutal. We've built the most punitive justice system in decades while creating the highest reoffending rates since records began. Every tough-talking home secretary has made the problem worse, not better.

This isn't about excusing criminal behaviour. It's about recognising that a justice system with a 48.7% failure rate isn't delivering justice for anyone. Not for victims who see their attackers back on the streets. Not for communities dealing with repeat crimes. Not even for offenders trapped in cycles they can't break.

Until politicians start measuring success by how many people stop offending rather than how many people they lock up, that 48.7% will keep climbing. And more victims will pay the price for a system that's forgotten how to work.
