Taiwan Japan and Korea are police state? Didn't notice this. I noticed some cops helping a drunk guy into a tax. Also helping to find a lost cat. I guess this is what you mean by police state.
In South Korea the contact tracing led to people being found who were cheating on their partners. Some committed suicide. Moral questions aside, is that the world you want to live in?
I personally don't even use an Android/eyePhone any more to avoid that dystopia.
Last time I checked no other country locks up more people, at higher rates, in prisons it won't even let the UN inspect [0], than the US does. In no other country is one as likely to end up in prison as in the US.
Neither can I think of many countries where police are more heavily armed, literally militarized [1], while killing people at rates that can only be estimated, as there are no state or federal statistics on that.
Still doesn't stop some US Americans from seeing the "police state" everywhere, except at home.
Even after over ten thousand people were arrested, thousands injured, many maimed, protesting against exactly that police state and its violence that disproportionately affects black people and other minorities.
