We are done for as a free country.
Nothing else need be said.

The USA-PATRIOT Act renewal calls for the creation of a national uniformed police force:
"A permanent police force, to be known as the 'United States Secret Service Uniformed Division,'" empowered to "make arrests without warrant for any offense against the United States committed in their presence" ... "or for any felony cognizable under the laws of the United States if they have reasonable grounds to believe that the person to be arrested has committed or is committing such felony."
The new police are assigned a variety of jurisdictions, including "an event designated under section 3056(e) of title 18 as a special event of national significance" (SENS).
"A special event of national significance" is neither defined nor does it require the presence of a "protected person" such as the president in order to trigger it. Thus, the administration, and perhaps the police themselves, can place the SENS designation on any event. Once a SENS designation is placed on an event, the new federal police are empowered to keep out and arrest people at their discretion.
