A Pennsylvania judge has ruled Bill Cosby, the comic once dubbed America's Dad, is a sexually violent predator.
The label means Bill Cosby, 81, must undergo counselling for life and appear on the sex offenders' registry.

A judge made the ruling ahead of sentencing the comedian for drugging and molesting a woman at his suburban Philadelphia home in 2004.
At a retrial in April, Cosby was found guilty of three counts of sexual assault against Andrea Constand.
Tuesday's classification means he will need to register with state police and notify any community he lives in of his sex offender status, as well as undergo mandatory counselling for life.
Neighbours, childcare centres and schools will have be notified of his whereabouts.
The actor's defence team had argued the state's sex offender law was too severe given Cosby's age and the fact that he is legally blind.
The disgraced comedian's two-day hearing at Montgomery County Courthouse in Pennsylvania began on Monday with legal debate over the violent predator label.
Psychologist Kristen Dudley testified on Monday that Cosby showed signs of a mental disorder and was likely to reoffend.
In addition to the label, Cosby still faces a maximum prison term of 10 years after an agreement between prosecutors and his defence team, but there is no mandatory minimum for the convictions.
The Montgomery County District Attorney, Kevin Steele, called for five to 10 years in jail for aggravated indecent assault.
Bill Cosby's defence is pushing instead for house arrest.
In June 2017, Ms Constand described how Cosby, whom she viewed as a "mentor", gave her pills that left her "frozen" and unable to stop his assault.
In Ms Constand's impact statement, provided to reporters by the prosecution team on Tuesday, she said: "To truly understand the impact that the sexual assault has had on my life, you have to understand the person that I was before it happened."
Ms Constand wrote that she stopped eating, sleeping and socialising in the wake of the assault. She said she had been a "young woman brimming with confidence" before Cosby took that from her.
"Bill Cosby took my beautiful, healthy young spirit and crushed it. He robbed me of my health and vitality, my open nature, and my trust in myself and others."

Protesters rallied outside the courthouse for Bill Cosby's sentencing
The comedian was arrested in 2015 and a deadlocked jury resulted in a mistrial in June 2017.
This year's retrial occurred amid the #MeToo movement that has seen people worldwide come forward to share stories of sexual harassment and assault.
