The whole world is a police state now, but some countries are more free than other nations.

You could find countries with the least tyranny by looking at the Index of Economic Freedom.

Another way to find free countries is to look at the number of prisoners in a
country. While every country is a police state today, some countries are too poor to jail criminals. You would have more
freedom in a place where the government doesn’t enforce the law often or imprison people.
