An example of discriminatory acquittal is when jury nullification is used to punish female rape victims by allowing their rapists to go free. The same is true of female victims of domestic violence. The "appropriateness" of a female victim's behavior in court can a great deal to do with how a jury will act, according to studies on the subject. Another example is the 1991 case of Rodney King. King was an African-American man who was beat up by police officers on videotape. The jury acquitted the police officers of beating him up even though they watched the video in court.
