I am not one bit surprised by this, it will keep happening. Europe is no place for these people they don't believe in western values, freedom to criticise or have different views.
Apparently the murdered teacher opened up debate in his classroom, but of course you must not criticise Mohamed even though he was the Jimmy Saville of his day, sex with children, women taken as sex slaves. People need to wake up and read the teachings of this dreadful religion then they may understand why these murders keep happening.
Incidentaly how did an 18 year old lad learn to decapitate a person? not an easy task I would guess, who trained him?
