Some spotty "news" reports I am seeing are referring to one of the weapons the perp used at the Chinese New Year mass murder near LA as a MAC 11 semi-auto. Also noted was that a employee saw the perp trying to load or re-load during the incident and somehow stopped him (perhaps fumbling with a balky magazine?). Trivial in light of the enormity of evil and suffering the perp brought into the world, but just wondering how & why the MAC 11 semi-auto and how often MAC 11 semis are involved in crimes.
