Although technology, politics and superpowers have changed over time, the characteristics of a police state and its reasons for being have remained the same: control, power and money. Indeed, as I point out in my book A Government of Wolves: The Emerging American Police State, a police state “is characterized by bureaucracy, secrecy, perpetual wars, a nation of suspects, militarization, surveillance, widespread police presence, and a citizenry with little recourse against police actions.”
Just as police states have arisen throughout history, there have also been individuals or groups of individuals who have risen up to challenge the injustices of their age. Nazi Germany had its Dietrich Bonhoeffer. The gulags of the Soviet Union were challenged by Aleksandr Solzhenitsyn. Martin Luther King Jr. went head-to-head with America over racial segregation.
