I dunno. I'm the furthest thing from PC, but the military has educated all of us pretty thoroughly on this sort of thing, and the shock and shame could make someone very reluctant to confront something like this head on in the immediate aftermath. Not to mention possibly being still sick or under the influence of something.

Also... in the military, informing the "command" ie the company, would start all balls rolling, including the justice system. She may not have quite grasped initially that company might not address this in the same manner the military would. Most company's would probably not call the police, that would be left up to the individual. The military CoC has the right and duty to initiate the justice system on behalf of the victim; for a civilian employer that would probably be too invasive.
