Everyone knows Britain's prisons are in crisis. But here's what they're not telling you: the people suffering most aren't the convicted criminals. They're the ones still waiting for their day in court.

Untried prisoners - those held on remand before trial - self-harmed 9,128 times in 2023. That's a staggering 153% increase from 2021, when the figure was 3,599. (Source: Ministry of Justice, Safety in Custody -- safety-in-custody-self-harm-dec-23 -- 2_6_Self-harm_by_status)

These aren't people who've been found guilty of anything. They're individuals awaiting trial, held in custody because they were denied bail or couldn't afford it. Yet they're experiencing a mental health catastrophe that dwarfs almost every other group in the prison system.

The numbers expose a fundamental injustice in how Britain treats people before they've even been convicted. While Instagram alerts parents about teens searching for self-harm content, the state is presiding over a self-harm epidemic among people it holds captive but hasn't proven guilty.

What's driving this surge? Remand prisoners face unique psychological pressures. They're dealing with the trauma of arrest and the uncertainty of trial outcomes. Many haven't had time to access prison mental health services or build coping mechanisms. They're often held in the most overcrowded parts of prisons, with the least access to activities or support.

The 153% increase since 2021 suggests the situation is rapidly deteriorating. Court backlogs mean people spend longer on remand than ever before. Some wait months, even years, for trial. During that time, they're neither fish nor fowl - not free, not convicted, but trapped in a system that's failing to protect their wellbeing.

This isn't just about statistics. Every incident represents someone in profound distress, someone the state has a duty of care towards. These are people whose guilt hasn't been established, yet they're experiencing harm at rates that would trigger emergency interventions in any other context.

The contrast is stark: while society debates how to protect teenagers from harmful online content, we're overlooking an actual epidemic of self-harm happening in plain sight. The difference? These victims are behind bars, out of mind, and presumed guilty before trial.

Something is fundamentally broken when people awaiting their presumption of innocence are harming themselves at record rates. The question isn't whether Britain's justice system is in crisis - the question is whether we care enough to fix it.
