In the news today

[Animeniax]

Your own words (emphasis mine): "If CNN is to be believed (questionable at best, admittedly)..."

Come on, we both know better than to believe the network famous for how often they fail, and given the statement I make above about the Chechen Radical Muslims...still bullshit. This is the same network that reported the Lord and Taylor camera captured an image of a "dark male" [LIE] and that an arrest had been made [LIE].

They have no connection to the Chechen insurgency.

I was playing into the Daily Show lambasting of CNN, but other outlets like HuffPo and the Daily Mail (UK) have also confirmed the link between the brothers and Chechen muslim radicalism. Maybe if you tried other sources for news besides Fox, you'd see that real journalism tries to support its claims with fact, instead of just yelling.

The Chechen insurgency is/was originally more about nationalism, but more recently it's been about Islamic fundamentalism. So the brothers' terrorist attack most certainly has ties to Chechen Islamic radicalism.
