I agree, tho. He could have just yelled at her to drop the knife. (Although if she was a wokeavist herself and hated the police, she probably wouldn't have listened. In that case, she would have totally deserved it.)
Well, he could have not shot her at all, he could have just yelled. . . (never mind, I just said that) And she didn't deserve to die, but what on earth would make her try to stab someone?
