Different police states have different shapes, and any difference we have from the others is a different in degree, not a difference in kind.
For example, we don't have a network of informants, no neighbors squealing nor children tattling on parents, instead we have a government agency that records every phone call made in the country, and every email. The IRS openly targets political groups that oppose the party in power. Administration officials call people who oppose their plans "economic traitors", and while, no, they aren't being shot yet, the president maintains his right to unilaterally order assassinations.
Are we in the top 3 worst police states? No. We don't even have a fleet of execution vans. We can still pull back from the edge, maybe, if people wake up in time. Maybe.
