We may never know. The people in charge are setting the agenda now.
CNN just now: “We have no evidence their religion or place of origin has anything to do with their actions, this is for information only”.
Also, listening to their anti terrorism expert, this is America’s fault. They see images of mosques defiled, women raped,Iraq, Gaza, etc. and they decide to act.
true indictment of the media and our educational system.
