Now how about YOU explain why modern Germans are still apologetic for the Nazis?  Or why we have collectively taken responsibility for what our forefathers did to native peoples in this country many generations ago?

As for 'however there has been nothing yet that links this incident to Islam or any other relgion':  give it a couple of hours, indications are that my odds are better than yours.
