No. It's about a nutter being a nutter. At this point in time no one has any reason to believe it has anything to do with his religion, skin colour or indeed sexuality, gender identity, left-handed-ness, hair colour, favourite colour or any of a whole list of factors which, as far as is known, have no bearing on his actions.
I think the real question, the question that goes unasked most of the time, is this: shouldn't we be expelling all foreigners, or at least all muslims, or simply killing them all? Why keep starting these 'latest news' threads? Drip drip goes the tap. Ask the question, once and for all, stop teasing, and seek a final solution, surely?
