What to expect at Bill Cosby sex assault trial
US comedian and actor Bill Cosby is
to go on trial for sexual assault in Pennsylvania later in a case that
is expected to last about two weeks.
Former University employee Andrea Constand alleges the 79-year-old drugged and molested her in 2004.
Mr Cosby says he is innocent and the encounter was consensual.
It is being seen as the biggest US celebrity trial since former American football player OJ Simpson's murder trial in 1995.
Several
of Mr Cosby's co-stars from the 1984-1992 sitcom The Cosby Show are
expected to attend the trial in Norristown outside Philadelphia, along
with more than 100 journalists. Broadcasters and photographers are
expected to camp outside.
What is he accused of?
Mr
Cosby faces three counts of aggravated indecent assault. Each count
carries a maximum sentence of 10 years and a fine of up to $25,000
(£19,500).
In 2004 Ms Constand was 31 when she visited Cosby's
home seeking career advice after befriending him through Temple
University in Philadelphia, where he served on the board of trustees.
She
said Cosby gave her three blue pills which made her legs feel "like
jelly" and that he then began to touch her inappropriately.
In 2006, the comedian settled with Ms Constand after providing an undisclosed cash sum to her.
At least 50 women have accused Mr Cosby of sexual assault, but he
only faces charges in Ms Constand's case because of statutes of
limitations.
What is the evidence against him?
Prosecutors
are expected to use the testimony of Ms Constand as well as that of
another woman, known as Kacey, who says she was assaulted by him in the
1990s.
They are also expected to refer to Mr Cosby's own
admission in 2005 that he had used drugs as part of his efforts to have
sex with women.
The drugs, called Quaaludes, are a sedative that was widely used recreationally in the US in the 1970s.
However
Judge Steven O'Neill has ruled that the court will not hear about the
2006 civil case. Neither will jurors hear from Mr Cosby's many other
accusers.
What is Mr Cosby's defence?
Mr Cosby says his encounter with Ms Constand was consensual.
He also says he offered women drugs as a way to encourage them to relax rather than a way to render them helpless.
On the night of the alleged sex assault, Mr Cosby says he gave Ms
Constand some Benadryl, an anti-allergy medication that can cause
drowsiness, because she appeared stressed.
Mr Cosby's lawyers are
expected to ask Ms Constand why she returned to Mr Cosby's house after
she said he had made previous unwanted sexual advances on her.
They
may also question why the case is being brought now, more than 10 years
after a previous district attorney decided there was not enough
evidence to go to trial.
Will he testify?
No
- Mr Cosby has said he will not testify and last month told Sirius-XM
radio that he feared prosecution lawyers could twist his words on the
stand.
"When you have to deal with examination, cross-examination,
et cetera, et cetera, more than two sides to every story - sometimes
it's four or five," he said.
He has also speculated that some of the allegations against him could be motivated by racism.
Who is on the jury?
The jury is made up of seven men and five women. They include two black people and 10 white people, the New York Times reported.
The
jurors are from the Pittsburgh area, 300 miles to the west of the court
in Norristown, because Mr Cosby's defence team argued that jurors there
could have been affected by pre-trial publicity.
The jurors will be kept away from media reports for the duration of the trial.
Why is Bill Cosby important?
Mr
Cosby is best known for his role as the father in the television hit
The Cosby Show, which was a huge hit in the US and around the globe.
At one point he was the highest-paid actor in the US.
He was born in Philadelphia and started his career as a stand-up comedian in 1962, debuting on NBC's The Tonight Show in 1963.
In
1965, he became the first black actor to star in a drama series in the
US, in the espionage show I Spy. He earned three consecutive best actor
Emmys for his role, at a time of high race tensions in the US.
In
2013 he did a national stand-up tour and received rave reviews. After
that, several women began to come forward with allegations of sexual
assault, some going back nearly 30 years.
