I meant more in terms of overlooking the potential for my mother to be abusive. Not that they thought that my father was abusing me, but that that's the only avenue of abuse investigated. Like being asked how my father treated my mother but not vice versa as a way of checking if I'd grown up around domestic violence - you'll get a false negative on the question "did I grow up around domestic violence" if you do it that way. Or overlooking potentially dubious things my mother did, or my own reports of how I felt about her, where they wouldn't have been overlooked if I'd reported that my father behaved the same way.
