This is the Guardian.

Today, a serving police officer has been revealed as one of Britain's worst sex offenders.

The Metropolitan Police could have stopped him, so why didn't it?

A warning before we begin, this episode does contain discussion of sexual violence,

but some listeners may find distressing.

On Monday, PC David Carrick admitted to 85 serious offences against 12 different

women, assault, false imprisonment and dozens of rapes.

Yesterday was a dark day for British policing and the Metropolitan Police as an officer

admitted being responsible for a monstrous campaign of abuse.

It's a story that is as disgusting as it is enraging.

Where was the vetting? Why were the multiple allegations made against Carrick across 18 years,

not taken more seriously?

And how was an officer whose duty it was to protect, able to pose such a dangerous,

nightmare threat to the public? Following Carrick's guilty plea, the Commissioner of the Met Police

apologized.

All I can say is, I'm sorry, I'm sorry that we've let you down and you have my absolute word.

We're going to remove this about sorting this out.

He said reform is coming.

But every time we get a case like this, particularly when it's ghastly as this,

it is going to shake that confidence. I recognise that and I'm determined to confront it.

But this isn't the story of one bad apple, all of a police force that seems to learn from its litany of mistakes.

And across the political spectrum, there is outrage.
