Its sad that the question at this point is, Was it crazy Americans with assault rifles or ISIS terrorists?
The fact that we can no longer tell the difference is sad.
The fact there were three shooters suggests organization so crazy is out. The anti-government militia types would be more apt to go after a solid government target than a quasi-maybe kinda sorta government target involving disable people.
That leaves you know who. But it's speculation at this point.
