Yet HMP Wandsworth shut SVI down the day following my announcement that the police were coming in. Why? The official reason given didn't add up.

And it was so successful, main players even volunteered to engage with top police and the police felt safe enough to come in and reciprocate!!
Far from being depressing, it was a beautiful thing and made people safer with formerly unreachable main players and their hitters and soldiers getting involved.
This one really brings it home for me. I started as a teacher in prison. Violent prisoners then began to volunteer to come to the discussion sessions I ran and that’s how SVI began.
Time to rethink prison safety: not just with more force, but with evidence.

With violence rising and talk of arming officers, ignoring evidence-based work like SVI makes no sense.
If something works in violent environments, it should be a starting point — not a casualty.
SVI was so successful, I was even able to persuade Wandsworth’s main players to agree to sit down for dialogue with senior police.
But when I told Wandsworth management about this astonishing breakthrough, they shut SVI down the very next day.
Why?
SVI used a “seeing-is-believing” model: prisoners met face-to-face, resolved tensions, and safely coexisted on the same wing.
Standard practice — segregation — only delays violence rather than resolving it.
Over a decade at HMP Wandsworth, not one single act of violence occurred between active SVI participants — during or between sessions — despite many having previously been directly violent toward each other or affiliated where violence had occurred.
It only required one member of staff to run it — me. In 2008, SVI won the award for innovation from the largest therapy organisation in the UK.
SVI was never an offender rehab scheme. Its sole aim was prison safety.
Here’s the critical fact…
The government is investing more in specialist teams to tackle serious violence. But years ago, there was Shame/Violence Intervention (SVI), which maximised prisoner involvement — enabling violent prisoners at HMP Wandsworth to come safely together.
