IIRC, that clip is dated 2 days after the murders. The story changed since then, for real or not.
There had to be a lot of shell casings on the floor. A .223 is impossible to mistake for a pistol round. How the initial radio reports from inside focused on handguns has to reflect the casings. I think.
Something appears amiss.
Loyalty to petrified opinions never yet broke a chain or freed a human soul in this world — and never will.
