The links between Dutch Greens(have they been expelled from the movement like the Mexicans?) and a political
assassin:

(…)
A politician of the Greens in a nearby town of Wageningen, a hotbed of Green and animal rights activism, an acquaintance of Volkert hears the news that Fortuyn has been assasinated. His name is Jack Bogers and he is a Green Alderman. He makes a phonecall within minutes after the assasination to a friend of Volkert, Sjoerd van der Wouw, working for the same organisation as Volkert. Sjoerd van der Wouw enters the house of Volkert and erases the hard disk of Volkert’s computer.

Obviously Sjoerd and Jack suspect or know that Volkert is the killer of Fortuyn. At the time the identity of the killer is not known and there is widespread speculation that it is a Muslim.

Only the next day the police search the house. They still found some clues, amongst other things plans and blueprints of buildings and premises of targeted firms.

It looks as if Volkert was a tool for other people who knew what he was up to and what he was capable of and did not want him stopped. Fortuyn was threatened and had asked the Ministry of the Interior for protection against assasination. This protection was denied by the Minister himself, Labour politician Klaas de Vries. Fortuyn had also said on TV that if he would be shot the blood would be on the hands of the politicians denying him protection.

In conclusion: Klaas de Vries was in charge of the police, which had the arrest team ready to apprehend Volkert as he killed Fortuyn, but which did not search Volkert’s house until at least some of the evidence had dissappeared.

And Sjoerd and Jack, the Green aiders of Volkert were never prosecuted.
