A very thoughtful response so I will treat it with respect.
You created a plausible scenario but it contains very little proof. I can create literally dozens of scenarios that fit the "facts" that you believe to be true. One obvious one, the AV took two or three percocets before she arrived at the party (a sort of Dutch courage) and they kicked in while she was there or she took drugs while changing in the bathroom. I need not create a felony out of very little to explain the facts you describe.
I would concur that if the team was charged with saying mean, inappropriate or nasty things the preponderance of evidence would make them guilty. They might even confess. But based on what we've seen so far drugging, hitting and waving Johnsons have very slim factual support. My personal theory which unfortunately has only as much evidence as yours is that they were fighting with the AV and Kim about the money for the very short dance.
The problem with the self-medication theory is that it does not address the consciousness of guilt evidence, i.e., the comment to the cabbie that she is just a stripper and the clearing out of the house.
I realize that these two matters are merely consistent with guilt and hardly proof of it. I don't see proof on the horizon. I like my theory because it ~~sweetly~~ meshes with all the facts. Nothing from a credible witness has to be blown off.
If it were only a fight about the money, one would have expected the strippers to have been more together in their response. Of course, some say that if one was drugged they both had to have been. I don't see that.
