Other than the bombing taking place at her venue, I don't see how this skank factors into this one way or another.
At the risk of being serious for a moment, she factors in because of the people who go to her concerts -- apparently, girls between the ages of 8-15.
I think these girls were deliberately targeted precisely because they've always been seen as the most vulnerable and most worthy of protection. I suspect that in violating them that way, the bombers hope to elicit a rabid response that will bring more jihadis to their cause.
The challenge for the British authorities is to hunt down and kill these animals without stirring up unrest in their Muslim population at large. Their experiences with the IRA may have taught them a thing or two about how to approach the problem.
