I won't question whether they just, blamelessly, "did their job" or not, simply because I can't possibly decide in a couple of minutes, from Barcelona, what others in America would need days, weeks and months of legal paperwork to try to clarify. But it is true that their business, apparently, is medicine, not porn.
The problem is that they present themselves as the INDUSTRY's medical association, not even the workers', and whatever they do and whatever their intentions are, will always appear more suspicious than if they were just a healthcare foundation working with the adult industry as with any other sort of professionals. So the case about that guy's infection could very easily derive into a case about "smut peddlers and their attendants".
