I think they're going to use the "he didn't comply with her commands" line to blame his death totally on him.
They'll admit that, yes, she made a mistake in going to the wrong apartment but as soon as he saw she was a police officer in uniform it was his obligation to do everything she said. He didn't, therefore, because she was in fear for her life, her weapon was discharged which lead to the death of the subject.
So she'll get a slap on the wrist, the family will get a big payout and we'll all forget about this in a few months.
