Because the bill prevented federal agencies from requiring public access. The people doing the research could have provided public access but they could not be required to provide that access.

I did read it - did you read the post I was replying to. He said "Ask those same people about having THEIR face superimposed on a nude child's body and see how their answers change." This is a totally different and clearly illegal activity because now there was an actual child harmed. I said the more interesting question is asking the people who thought it didn't break the law if their opinion changed if it was THEIR CHILD's face on the nude adult body instead of Miley Cyrus's.

Reading comprehension - not just to be applied to the article.

But that appears to actually violate the law in question - because in that case there is an actual minor involved in a simulated sexual act. The better question to ask is if their answer changes if their childs face is superimposed on a nude adult.
