No, if the police shoot someone it's because a buck-naked man reached for his waistband.
They ain't even trying to come up with a decent lie anymore. It's "I was in fear of my life." The very fact that they use the awkward grammar and preposition, rather than "for" the obvious choice of a middlin'-educated English speaker, demonstrates that it's a rote-memorized line.
Hell, our cops have so much impunity they don't even bother to carry throw-down pieces anymore.
