Were the deaths of 20 "armed rebels" during september 11 2001 and the consequent killings in Pakistan a failure the Usonian government?
Was the cause of the twin towers collapsing and ~3000 dying, a result of Usonia being too much of a police state?

Or why not go to something more recent, is the armed rebellion since 2014 in Ukraine,
that's more recently backed by Russian troops, against Zelensky,
an example to you that Ukraine is a police state?

I’m sure if more armed rebels entered the capital it would have been incredibly messy and people would have died.

Is thus the Jan 6th insurrection an example to you of Usonia being a police state?

And killing a ton of people, regardless of why, is a failure of government.

So if a government A declares war on government B and starts to use lethal force, it's a failure of government B if it decides to kill the invading army?
What if government A has a drug policy to keep as many people addicted to a drug in government B and if government
What if government A decides to support a destructive religious cult in government B and these people start to violently suppress any form of criticism against them while infiltrating key political positions?

And does a "failure of government" automatically mean that such government is a police state?

Conflating one violent protest with another and then saying “Usonia Evil so China Good” is inane.

No, what's inane is to conflate the actions of a government that uses lethal force to respond to terrorists doing terrorist acts at a protest with legalized murder by car to any protester that blocks a roadway, have your secret police shoot and arrest anyone who films during a protest including journalists, have your secret police force migration of the homeless and of legal immigrants and citizens deemed "culturally inferior", by calling them both police states.

You are not living in a totalitarian police state when your government is failing to arrest a terrorist group carrying dozens of petrol bombs during a protest that was going on for months on end. A police state would suppress the protest on day one, which is what Usonia is doing to pro-Palestine protests. A totalitarian would surveil all protesters on day one, which is what Usonia is doing.

Usonia is experiencing indirect pressure from another country for the first time in history,
indirect pressure that is extremely mild and yet I would argue it's reaction was to immediately put a fascist into power and go further into fascism than Nazi Germany. Nazi Germany tried to genocide all Jews, Usonia seems to target the whole planet except for the Zionist Jews.

Usonia harbored an extreme "we are the exceptionally freedom people" ideology, an off-shoot of the century earlier "we are the exceptionally civilized people" ideology, but now due to the extremely mild external pressure, Usonia has gotten far worse and made a 180 degree turn to every rule it imposed on other nations for itself and now forces other nations to follow.
Even worse, it's gone so far as to flip these rules again on a daily whim, if not every hour, minute or second.
Nazi Germany did not do that.

Nazi Germany at least seemed to care somewhat about its own citizens.
MAGA Usonia seems to want to starve its own citizens to death, even the vast majority of its own supporters seem to be inferior creatures not worth living in the eyes of the Usonian oligarchs.
