With ISIS reeling from Iraq and the most likely death of its leader, global terrorism may well evolve, sadly, into being a greater number of attacks with more amorphous, random targets (see this article by Simon Mabon http://tinyurl.com/ydyan3lo ).
Already the WSJ had reported on smaller, often bungled attacks in Europe in a new phase of global terrorism http://tinyurl.com/y7yjkg4s .
Ironically, this may make it harder, rather than easier, for free societies to protect themselves from attacks by lone wolves, with less coordination and communication among less experienced terrorists. And, of course, with potential terrorists protected by constitutional freedoms, the incidences of attacks by so called “known wolves” may also increase. These are previously arrested suspects who could not be held in custody because of “actionable” evidence or activities.
