We seem to be moving in this direction and should take these blatant abuses of power and public demonstrations of force as an indicator. Of course, the heavy militarization of police across the country is another unavoidable sign of a shift in that direction.
This has to be met with resistance and strong condemnation before that becomes a crime, too. This not the kind of behavior that is acceptable in a democracy and it is a threat to freedom.
A police state is a government that exercises power through the power of the police force. Originally, a police state was a state regulated by a civil administration, but since the beginning of the 20th century it has "taken on an emotional and derogatory meaning" by describing an undesirable state of living characterized by the overbearing presence of the civil authorities.[1] The inhabitants of a police state may experience restrictions on their mobility, or on their freedom to express or communicate political or other views, which are subject to police monitoring or enforcement. Political control may be exerted by means of a secret police force that operates outside the boundaries normally imposed by a constitutional state.[2] Robert von Mohl, who first introduced the rule of law to German jurisprudence, contrasted the Rechtsstaat ("legal" or "constitutional" state) with the anti-aristocratic Polizeistaat ("police state" .[3]
