From an interview with Professor Hans Jansen on Radio Netherlands:
"... I think they should look for the accomplices much closer to the home of the murderer. I mean, Muslim assassins that kill in the name of Islam usually consult a Muslim lawyer - a Mufti or legal specialist of Islamic law - and ask him for his advice and for his opinion. Because otherwise, it would mean that the commands of the Koran to fight the unbelievers would simply boil down to one believer killing an unbeliever, which of course would not work - it would create chaos and total idiocy."
"No, you can only wage Jihad, engage in holy war, or whatever expression you prefer, once this has been analysed and permission is given by competent Muslim legal scholars."
"The Amsterdam prosecutor said on Friday that the charges against the seven suspects arrested on Tuesday included "participation in a criminal organization with terrorist aims" and "terrorist conspiracy" for the murder of Van Gogh as well as plans to kill liberal politician Ayaan Hirsi Ali "and others"."So, when you look at it from the outside, it would be against the laws of Islam - and the laws of Islam are very strict – to act against this. Now, this man wants to pose as a super-Muslim, so he probably obeyed the laws of Islam. Accordingly, it's really very important to find the expert on Islamic law who gave him permission to commit this act. Because this expert is of course as guilty as the murderer himself."
