Police in the US is just a reflection of the failed democracy that is the US.
Their police are trained to deliberately escalate situations. This is a deliberate act. They also have ZERO accountability for any crimes they commit. Most DA do not press charges and the few that do, get threatened with police boycotts which eventually leads to the officer getting away with it. Police training is also frequently only a few months. I've heard of 3 month trainings, even. That is absurd. This leads to many psychopaths being attracted to the position as it has all the hallmarks. Power, prestige and zero accountability.
I've seen videos where the the guy is on his knees begging not to be killed, hands in the air and the officer is screaming at the guy as if the officer was being threatened. Giving the guy contradicting orders and threatening to kill him. When the guy is confused, he gets shot to death. No charges. And lifetime police pension for the prick because "he has PTSD".
The racism is very obvious. With huge differences in how they deal with black people compared to white people. That Kyle Rittenhouse case is a golden example.
The police are also overly militarized with many having receiving ridiculous amounts of military firepower and equipment. And trigger happy pretenders hoping to be able to use their new toys. Not being trained to use such weapons and equipment in the first place.
They seriously need a police reform. Police training needs to be extended to a few years of training. Training must emphasize on de-escalation. Not escalation. No more war tactics on civilians. Police must be held accountable for any potential crimes committed. Investigations performed by a 3rd party answerable to state legislature. All investigations made public and police body cams released publicly on a daily basis as protocol. They need to demilitarize the police force with a total banning of military firepower being obtained from military surplus programs. No more assault rifles. No more tanks. The culture needs to be changed. Police chiefs must be removed if they resist any of these reforms. Culture in an organisation is always top down.
