So we're saying theoretically, the NZ shooter made no statement of contact with another or indication of any on his stream/chan post that it was a twofer event.

If anything, his chan post makes it clear it's "one lone nut".

But there are two mosque shooters at the exact same time…

Hmm.

So there is now a reported shooting at the hospital where the original victims were taken?

Along with this second shooter apprehended (I'm thinking camo guy, Sandy Hook type) while orig shooter dead.
