What’s the significance of this? I’m not being difficult, just dense and trying to understand what this means.
The Youtube link indicates there was some relationship between the maintainer of Gifford’s page and the shooter, Loughner. The videos at Loughner’s page are about peculiar topics like sleep walking, mind control, and flag burning. Having such a link on a Congressman’s page would be odd even without the shooting.
This means that someone with access to the Giffords account logged in, visited the Loughner profile and clicked “subscribe” to follow it.
The question is who and why.
This is a potentially pretty big - as an investigator I would want to know the answers to both questions because it could signal beforehand knowledge of Loughner or the threat he posed.
