From full statement - linked above -
As of this release, there are a total of 44 shell casings recovered from the Twin Peaks scene. This number does not include the revolver rounds fired by non-law enforcement shooters. Those casings are still being counted. 12 of those casings were from the rifles of 3 Waco Officers who discharged their weapons in defense of their selves or a third party.
What can that possibly mean - still being counted.
I took it as those spent casings are in guns sent away for analysis.
Union counters, in the private sector, counting to twelve doesn’t take most of us very long, but you know how unions are.
