Major Hasan and Holy War EXCERPT: European counterterrorist officers know well that jihadists can appear, self-generated or tutored by extremist groups, inside Muslim families where parents and siblings lead peaceful lives.

Both cases allow little time and often few leads to neutralize a possible lethal explosion of the faith.
