The way I see this from your posts is that it breaks down into these issues:

a. Did she get AIDS on the shoot or elsewhere?
Let's keep in mind that in civil cases you don't need absolute proof. Just proving that she probably caught it on the shoot is enough to meet this hurdle.

b. Is the Threat of AIDS something she accepts for being a pornstar?

c. Is a Pornstar a temp or a contractor?
Temps have more rights than contractors. This is why a lot of companies are outsourcing.

d. The composition of the jury. She is going to look pitiful and defenseless for the trial. How is TTboy going to look?
