So you think cops only shoot .223? I know ATF buys it in 63 million round lots, but it’s not all that they buy. And Waco PD uses a variety of firearms.
But we do know that at least some of the victims were shot by the cops using .223: “evidence reviewed by The Associated Press now confirms that the gunfire included rounds fired by police that hit bikers, though it isn’t clear whether those rifle shots caused any of the fatalities.” http://kxan.com/2015/09/18/waco-police-bullets-hit-bikers-in-may-shooting/
“And Waco PD uses a variety of firearms.”
No indication that they shot anything other than .223 at Twin Peaks.
