But she was lying.
I learned my lesson then: The presumption of innocence means you should not assume the accused or the accuser is lying. Withhold judgment until you're sure all the facts are known.
Anyone who thinks the testimony of two women must be conclusive should read Who says women never lie about rape?:
'Thank goodness,' writes New York prosecutor Linda Fairstein in her book 'Sexual Violence,' '[the victim's] testimony -- when it is credible -- is all that is needed to convict a rapist, as it is any other criminal.'Finding examples of women lying about rape is surprisingly easy, and sometimes shocking:
But what is 'credible'? In 1996, Los Angeles police officer Harris Scott Mintz was accused of rape by two women who were said to be 'very credible': a woman in the neighborhood he patrolled, then his own wife. At a pretrial hearing, the judge pronounced that he had no doubt about Mintz's guilt. Then, Mrs. Mintz admitted that she made up the charge because she was angry at her husband for getting in trouble with the law; subsequently, Mintz's attorneys uncovered evidence that the first accuser had told an ex-roommate she had concocted the rape charge in order to sue the county, and that she had tried a similar hoax before. By the time the case collapsed, Mintz had spent five months in jail.

A number of blogs have been dedicated to the subject. Some of them are undoubtedly by bitter, sexist men, but the bigger question is whether they're right. Cry Rape - Beware Of These Liars seems to accurately collect mainstream accounts of false accusations of rape.
And there's always Wikipedia: False accusation of rape.
*ETA: I included the Kobe Bryant article because it's phrased as a question and includes relevant examples. When the case was dropped, Bryant made a statement: "Although I truly believe this encounter between us was consensual, I recognize now that she did not and does not view this incident the same way I did."
