Bill Cosby Goes on Trial, His Legacy And Freedom At Stake

Norristown, Pa. (AP) -- Bill Cosby went on trial Monday on charges he drugged and sexually assaulted a woman more than a decade ago, with prosecutors immediately introducing evidence the 79-year-old TV star once known as America's Dad had done it before to someone else.

The prosecution's opening witness was not the person Cosby is charged with abusing, but another woman, who broke down in tears as she testified that the comedian violated her in the mid-1990s at a hotel bungalow in Los Angeles.
