No, nothing on race or color. But the fact that the FBI said that the aren’t ruling out terrorism, and the chief said “it may be or may not be terrorism. We will go where the evidence leads” kind of tells me the answer. They also had explosive devices in the vehicle and at a home that was searched. Does not sound like a pissed off party-goer.
Doesn’t the fact they avoided race or color tell us something?
It tells me something.
