The shooters could be “Islamophobes” who screamed “Allahu akbar” mockingly. Or they could be Muslims who were firing upon other Muslims whom they deem heretical: a Sunni-Shia dispute, or adherents of the Islamic State versus opponents of it.

In any case, this is being covered as if it were an “anti-Muslim hate crime,” and it may be. However, this story that notes that the gunmen were screaming “Allahu akbar” is notably free of the laments about “Islamophobia” that were in earlier stories about the shooting. There is no certainty at this point that it was an “anti-Muslim hate crime,” and the screams of “Allahu akbar” open up the possibility that this was yet another “anti-Muslim hate crime” committed by Muslims.
