I took it as those spent casings are in guns sent away for analysis.

That makes some sense. I wonder how and where they found 11 additional rifles?

Good question. I would speculate most of them were in cars/trucks, but who knows how many were 'standard equipment' inside the restaurant.

I wonder if the full-auto, suppressed firearms used by Waco PD have brass catchers. I don't think that changes the count of brass, or number of shots claimed to be fired by the Waco PD, just curious.
