Yes. The police make bad decisions, too.
Do you think it is possible the police may have had probable cause and it is the couple who were lying about what they were doin? That perhaps they went well beyond what is considered in good taste, even by Hollywood standards?
It's possible, but being possible is not the same this as having actually happened, or even having been proved to have happened. Do you have proof that this actually happened?
Said actress was on CNN and the large black female actor sked her what she was doing in the car, and she would not say... Case closed, IMO, she was having some time of sex.
