Remember, this woman who claims to have been 15 at the time also says that a 16 year old ‘friend’ was with her and Cosby at the mansion and ‘given’ alcohol’ by Cosby.
So that makes at least 2 minors that somehow got into the mansion where ADULT ONLY activities occur.
How could this be ?
I can imagine a couple of ways. I read the complaint, and if I understand it correctly, it implies (though does not specifically state) (cf. Huth v Cosby complaint, p. 2) that the minors were driving a car following BC’s car to the playboy mansion. It sounds as if there was no guard since the complaint states only that BC advised them to lie about their ages to playboy bunnies, not guards. Beyond that, it seems that no law required an age check to the premises of the playboy mansion. I think the playboy mansion might have been a relatively unusual place in the LA area, and that it might have escaped legal regulation by informal means (eg, having playboy bunnies informally looking out for underage minors). This is just a guess...
According to the complaint (p 2), if I read it correctly, BC allegedly gave the minors alcoholic beverages at the tennis club, not the mansion.
Here is the complaint so you can read it in full and form your own opinions rather than rely on someone else to read it and try to interpret it for you:

Why don’t you take a look at it and answer your own questions? :-)
