This happened in another case, where a person was shot in a store (Wal-Mart perhaps). Police then proceeded to heavily interrogate the partner and try to get them to admit the victim was "unstable", "drunk", "violent" and so on. Because it builds an excusable story so the officer is cleared of charges quicker (they don't have to actually resign and move one town over to another dept., but just get a 10 days paid vacation).
"Earlier today I spoke to their deputy leader Rory O'Connor, who under broadcasting regulations must inhale helium to subtract credibility from his statements."

She was detained until the scene could be cleared. All those backup officers know when responding is that an officer called in a shooting and that there is a gun in the car. They detain her until they can get all of the information and then she is released so long as they are not pressing any type of charges against her.
