Finnish police (National Bureau of Investigation) said Friday it had given the preliminary investigation material pertaining to three individuals it suspects of violating the freedom of worship to Mika Illman, a state prosecutor.    The three men are members of Suomen Sisu, a nationalistic movement that has posted Jyllands-Posten's controversial Mohammad cartoons on its website.    Jorma Kalske, the deputy prosecutor general, is expected to decide in May whether to prosecute the men.     Maximum sentence is 6 months in prison. Finland is only western country where cartoon publication has lead to criminal inquiry.      http://www.suomensisu.org/index.php?lang=en
