I can see that, but the Atlantic piece still attributes the attack to Isis. Now why the SL government feels it necessary to claim that, I don’t know. Though I think this interesting:
>>When the 50 Muslims were shot in Christchurch, the world probably seemed more ripe than ever for an ISIS resurgence, to show that the group remained deadly. That ripeness is more likely to have influenced target selection (as Brian Fishman notes) than to have initiated an attack where plans for one had not previously existed.<<
