Depends on context, obviously. The police officer has the responsibility to constantly assess the situation in order to determine if violence is warranted, as well as if that violence needs to be potentially lethal, regardless of whether or not a person is complying. As an office, one doesn't have the right to commit bodily harm, nevermind kill someone, without good cause. Hence why people talk about it so much, and also why people like to talk about police brutality even when it's regarding people that don't comply with officers (eg. protesters, bystanders, people filming, etc.) Example: this classic https://youtu.be/7Ooa7wOKHhg https://youtu.be/7Ooa7wOKHhg. Shit like this happens in the States all the time, it's just not usually as bad, nor televised. But situations with power mad cops crop up all the time. Cops that forget that they are an arm of the law, rather than the law itself. I don't know how the case mentioned in the article holds up though as I'm not aware of details.
