It is odd to me that, of all people, some Europeans seem to have forgotten what a true police state is.
When was the last time someone was shot to death trying to escape from the United States? When was the last time someone was denied an exit visa from the United States? When was the last time someone was jailed for criticizing the US President?
Does the US legal system have problems? Yes, it absolutely does. The same is true of every country, to a greater or lesser degree. But the US is not a police state. Eastern European countries during the Soviet Era were police states, and as European citizens, you, of all people, should know the difference.
Calling the United States a police state undercuts whatever point you were trying to make.
