Ten rounds now? I really must try harder to keep up. Recently, it was 12 rounds the police claimed they fired, likely semi-auto, rifles with decent sights, from good positions.
Any word on which of the dead/wounded was shot with what?
Nope. Nor do I know how many rounds of fired brass were recovered from biker's revolvers, (to add to the pile of bikers' ejected pistol brass) either...
(FYI & FWIW, I'm really not "on top of" the case -- just happen to have a friend who was in Waco when it went down...)
