This is a propaganda meant to diminish the influence of Islamic thinking in the actions of these terrorists.
Third of known French radicals are mentally disturbed
Nearly a third of people on a French terror watchlist are believed to have psychiatric disorders, Interior Minister Gerard Collomb said Tuesday, a day after a mentally ill man went on a rampage in a stolen van in Marseille.
The incident, in which the man drove into two bus shelters, killing one person and seriously injuring another, immediately drew comparisons with a string of attacks across Europe in which vehicles have been used as killing machines.
But investigators said there was no evidence of any terror links, saying the 35-year-old French driver who had a book about philosophy and another about Islam in the car, had “psychological” problems.
