To me it reads that you are suggesting a race bias on the reporting of a crime perpetrated by a white person against Muslim people, whereas if it were the other way round it would be a "terrorist" attack. In.which case I would wait and see hat is reported before making this conclusion.
However, however this is reported, what an awful tragic case, that poor boy has likely.lost parents and a sibling, there are no words for what he must be going through.
