There is such a sensational case, but you will hardly hear details about it because it involves a pair of Muslim influenced killersshooting what they called "white devils" on behalf of one "Allah". These are the Beltway Killers who terrorized the Eastern USA a while back. The leader was John Muhammed and his acolyte Lee Malvo. Ample evidence was produced at the trial of the religious nature of the serial killings, including notebooks and other writings. Bin Laden was featured heavility in Malvo's notebooks as a "Good Muslim". Malvo confessed to Islamic indoctrination from Muhammed who repeatedly talked of "shooting white devils" at a level of six victims a day, if possible.
Going by stories on the BBC, AP and other agencies there is no mention whatsoever of any link with Islam in the John Muhammed case. Even minor media like the Richmond Times Dispatch of Virginia where the shooting occurred merely mention "indoctrination", without using any further description of what kind. The 'Religion of Peace' is unmentioned.
One victim of the shootings who survived still does not understand. He tells the Richmond newspaper,
"I never expected to understand 'why' they were doing what they did -- it's not socially rational behavior -- but I did find a sense of closure in hearing 'what' they were doing."Even by Koranic standards, it was not religiously rational, but that religious impulse was the fire that stoked the killings.
