Probably because she actually did give him the information, although she carped about it later. Reluctant compliance is still compliance.
It was and is NOT her decision to relay information to the sheriff. She is (should be was) and employee of the county and it her duty to forward information to the TOP LAW authority in her county. End of story. When the dust settles, the sheriff could fire the dispatcher for not doing her job and MAY possibly be charged with obstruction. Might be interesting how that comes out.
