Nobody is taking Quaaludes to make anything "more exciting". They're a powerful sedative, not a stimulant.
This is simply a paper thin alibi.
Even with criminal immunity he didn't want to openly confess the real motivation for drugging his victims.
My point was that they consented to have sex with him, and
consented to take the pill..
Presumably some girls said no thank you and left. None of these women were questioned.
Slipping a pill into a girl’s drink without her knowledge and then having sex with her when the pill sedates her is a crime
Having a girl claim rape for activity that she had agreed to and then changed her mind is a gray area.
Naive college girls do this all the time...
But these were grown women so presumably knew what they were doing.
