I don't know if I'd put too much credit in that. As soon as Shep read his name on Fox News, bogus Facebook pages started popping up all over the place.
Not saying it isn't true, just that many of those FB pages were obviously fake (including, I'd imagine, the ones that had Loughner describing himself as a fan of Sarah Palin and Glenn Beck).
I saw it yesterday afternoon very shortly after the shooting. The blog that posted it said it had already been taken down and they couldn’t link to it anymore.
I believe you can still find it here on FR. It was posted yesterday.
