2013: Boston Under Martial Law: Shocking Footage Emerges

Was this just a 'dry run' for the imposition of martial law and a total police state in America?
FBI, Police and SWAT teams enforced door to door searches of everyone's home within twenty blocks as the entire city was placed under orders to stay off the streets.
The video, shot by a resident from their own house across the street, shows police barking orders at men and women as they order them at gunpoint to identify themselves, put their hands on their heads, and get out of their own home. They are then ordered to run down the street to be further frisked by police as scores of armed militarized cops look on.
