It's the law, and it's the foundation of a lawful society.
Sure... so long as lawful has nothing to do with safer or more ethical.
When police are trained to do anything they can to avoid danger to themselves, even if it means killing a suspect, that makes society more dangerous for everyone except police. Because innocent people need to fear for harm from criminals and police, instead of just criminals. If police don't want to put themselves in danger, they can not sign up for the job. Because otherwise, we are better off without them. I would rather face a violent criminal than a power tripping or spooked cop, because at least I have the opportunity to defend myself against a criminal.
And it feels ridiculous to even have to explain why being legally forced to comply with all police orders in all situations regardless of legality or reason is flat out wrong. Even without the point that it's an expectation that gets people who are deaf, having seizures, mentally disabled, etc hurt or killed often enough.
Edit:
Ok yeah... I just made the mistake of watching that video. That guy was clearly terrified to the point of stupidity and even looked physically weak and near passing out from fear in those last few seconds, and the officer shouting orders was totally callous and made it as difficult as possible for him. He was shocked, then intimidated to the point of tears. Then given 3 separate instructions about body positioning that were counter-intuitive in combination (cross legs/hands up/crawl), and repeatedly shocked into panic when screamed at about how he would lose one position when trying to comply with the one most recently screamed at him. When someone thinks "crawl", they normally imagine using their hands. And this is after he was screamed at for uncrossing his legs when rising to kneeling, and then not told he could uncross them when instructed to crawl. When you're in the kind of emotional state that guy was clearly in, it's not reasonable to expect the level of focus necessary to work through that mess out of an average person. And they killed him for it.
I wouldn't call it murder. But I would call it stupid, cowardly, and unfit for the job. And I'd say that if the officer hasn't shown any genuine signs of remorse and making amends, that he deserves to be shunned by the people in his life. When I see things like this, even after so goddamn many, it leaves me shaking livid for hours, and wondering how the fuck anyone can still call police on mere suspicion of something without considering the likelihood that their doing so will result in the deaths of undeserving people.
