if you can stomach it i would recommend watching the body cam footage of the sonya massey killing, i'll try to describe it but it's hardly possible. you can't truly understand the type of extreme, completely volatile aggression that happens with cops if you haven't seen it, and it's captured here very harrowingly.
several officers are in her house, calmly talking with her about her id and vehicle papers for some time. it's routine administrative stuff, no acute danger or stress whatsoever. one of them tells her to take her pot off the stove, remarking that they don't need a fire in the house now, she walks over into the kitchen and complies. he suddenly backs off towards the front door despite already being several feet away. she asks him where he's going, he says "away from your hot, steaming water." she repeats "my hot, steamin' water?" in an amused tone. then adds "i rebuke you in the name of jesus," in a similar joking tone while pouring the water down the sink. the atmosphere is completely calm, you might even say amiable.
she's at this point still separated from the cops by her kitchen aisle and several feet of additional distance. the cop prompts her to repeat what she said, she repeats her joke about rebuking him in the name of jesus [with the scary water she just poured out]. she doesn't even realise there's been a complete 180 in his head. he goes "you better fucking not, i will shoot you in your fucking face," she's stunned by the sudden abusive language for half a second, immediately he draws his gun directly at her head, she gets out a panicked "sorry!" and ducks behind the aisle, he rounds the corner into the kitchen specifically to advance right next to her, immediately fires 3 shots at her head from above at minimal distance. she's dead where she stood, or cowered rather, by the sink in her nightgown.
after a few seconds you hear the click of him turning on his body cam, saying "she came at me with a pot of boiling water." for the recording. he also nonchalantly tells his partner there's no need to get a med kit because it was a headshot. it's one of the most clear cut cases ever and it's fully recorded only because his partner did already have the body cam on throughout.
