A complaint that two people were kissing? That amounted to probable cause? That it would have amounted to probable cause even if both parties were white? Sorry, I don't buy that.
Does it make sense to you that the police in the most liberal county in the most liberal state in the country, a place where morals is a quaint word from a bygone era, even 60 years ago, are going to react to some interracial necking?
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?
