I guess I'm not understanding why the defense can't ask what DM did and who she called before calling 911 IF the state asks her about calling 911. If the state only asks her about seeing a guy with bushy eyebrows that's one thing. But if the state asks her other stuff, why can't the defense question her on those other topics too? (While not being too "heavy-handed") I'm not suggesting the defense would ask her about what other people said to each other. But it would seem the defense ought to be able to ask who, if anyone, DM called and when that happened and when others arrived at the house, who those others who arrived were, and what she observed them doing. They may not choose to ask all of that but I don't see why that would not be allowed if the state asked about calling 911.
