Sometimes I think the denials come from an unwillingness to accept that they have unwittingly associated themselves with a person who is capable of such an evil act and that by acknowledging that they have come to realise that it is true they are somehow guilty by association. Other times (like it appears to be with Michelle Phillips) the constant denial comes purely from self interest - in that it would hurt her royalties, Chynna's royalties etc. Some people can't and won't see beyond their own wants and needs. I know of a case where a woman was told her new man was a convicted child molester and not only continued the relationship but also coached her kids not to say anything bad about him when child protection workers got involved but also went into nuclear meltdown against the third party who warned her and then reported her when she wouldn't ditch the guy. To her the fact that he treated HER well was more important than anything else. It still makes my blood boil to remember it and I will never be able to let my hatred of her die for what she exposed her kids to.
