Anything that cites an article you have to pay $50 just to view, is automatically suspicious, as far as I'm concerned.
Of the stuff I could read, that they linked... it boils down to "We don't know. We need more data." To which their view is "So let's do nothing, and never get that data, because... you know... please don't sue us, parents!"
It's a case of confirmation bias and clutching at straws. And I feel for the people living there who have to deal with this. Because it really kind of sucks.
