Look, I'm no Sherlock, but when a Muslim guy murders a whole bunch of people with a truck filled with ISIS propaganda, flags and hand written notes of commitment to ISIS, then prances about shouting "Allah is greater!" while waving guns, I'd kind of detect that he is a radical Islamic terrorist. I know we are now due for the usual gut full of warnings of  so called 'Islamophobic' back lash about the 'Religion of peace' and he was 'mentally ill'. But at least eight dead are a sure testimony that we can't go on ignoring this war on Western Civilisation. Hundreds of innocents have been murdered in the West just this year by these fanatics. So go searching  for a motive. Why not? If it was a snake it would have already bitten you.
