Exactly. I've read a story about a US police officer (a former marine) who managed to defuse an armed situation, and got reprimanded or fired for it.

So not only are (at least some) US police officers insufficiently trained to de-escalate potentially dangerous situations, they are actively punished when they do de-escalate. They are expected to shoot people.

Equally bizarre is that law enforcement experts warn people not to talk to the police without a lawyer. Not even as a witness or to help them. The American attitude towards police and police work is utterly alien to me.
