One horrific thing about this (one of many horrific things, granted) is how it's being turned into a political stick for the right wing press to beat the BBC and the NHS with. Those bastards didn't go after him for the same reason that it took 40 years to come out properly. Everyone knew the rumours, nobody had evidence. You can't just call someone out as a sex offender, especially not a "national treasure" (read: "armed to the teeth with lawyers"), unless you know damn well you can prove it.
They know it. They've practically admitted it. That they have the temerity to call the kettle black is fucking absurd.
