Lets try this again.  No I'm not saying the women had racist intent.  In the case of the 3 black athletes the woman was black as well.
I don't think race played a part in the evenings events at all.

Part of the public will make a presumption of guilt/innocence based on race.   A part of the public will make a presumption of guilt/innocence based on gender.  Do you doubt that?   

The police on the other hand based their actions on the evidence and found it insufficient to make a charge.  Did you read the report?
