As a result, we’re seeing lines blurring what were once more-distinct. Terrorist and non-terrorist incidents are becoming indistinguishable by their appearance and even their effect. And any given act of violence can be heightened to terrorism by the utterance of a few words as a perpetrator is arrested. If authorities simply declined to pass on those words there would be no obvious political message communicated at all. It’s a far cry from the carefully conceived plot with an easily-discerned symbolic target and some accompanying manifesto shouting at the world. Once there was no mistaking the political seriousness of the terrorist group. Now you need a team of psychologists to figure out if it’s more a rhetorical costume.
