Anna Lindh: Swedish foreign minister, stabbed to death in 2003 by a Serbo-Swede enraged by her position in the Kosovo War. The killer, Mihajlo Mihajlovich, was initially diagnosed as insane during the act, but this conclusion was overturned.

Theo van Gogh: Dutch filmmaker, stabbed and shot to death in 2004 by a Dutch radical Islamist with terrorist connections in retribution for a 10-minute film about suppression of women in Islam. On his body the killer appended a note which threatened Western governments, Jews, and the politician A. Hirshi Ali, on whose book the film was based.

The world's northernmost desert wind.

Mohammed Bouyeri, the murderer of Van Gogh, killed Van Gogh simply because of his own interpretation (the salafism/wahabism) of Islam. Bouyeri viewed Van Gogh as an infidel and, what's worse, an enemy of (his) Islam, giving him enough justification to slaughter Van Gogh. That's it. End of story. He was sane, he was perfectly rational in his own little fucked-up world, which he attempted to defend during his last case and the current one, the Hofstad case. In both cases, his  attempts to be a scholar of Islam texts were distorted, rudimental and selective, so say other Arabists.
