They don't use always the same tactic. Belgium, November 9, 2004 :

In Holland Pim Fortuyn went from 0 to 33% in one year, after having gathered the most votes in the Rotterdam elections.
They murdered Pim Fortuyn, five days before he would participate for the first time in the national elections.
Two and a half years later they are so afraid of Pim Fortuyn, that directing a film about him (Theo Van Gogh) is enough to be sentenced to death.
In the case of Pim Fortuyn a green activist in defense of animal rights was used to cover-up the murder.
In the case of Van Gogh they don't have to use this kind of fantasy : the muslim suspect is just a good reason to provide protection to mosques 24 hours a day with police. The protection that was denied to Van Gogh.
I believe teezle said he refused it, which would seemingly be in character. Where did you learn otherwise?
