This young male was undoubtedly brainwashed by the insane mullahs of hatred and death.
One or two of the links concerning the assassin suggest that he was put up to it by another person or group - most likely the anti-West, Islamic nationalists - because people his age are dealt less harshly by the law. His uncle said he had never been to Istanbul before and couldn't possibly have known his way around well enough to find the offices of Agos. He is also from the same town as the young man who murdered that Catholic priest a while back. There is definitely something more than meets the eye here.
Per your tagline. Racist is not a logical descriptor for Islamists. Their doctrine of hate and domination is based on religion, not race.
