Resistance: the battle of philadelphia
A Speculative Chronology of a Police State (4 of 5)

2029:
A former general in the previous administration is elected president. He assigns troops to “trouble states.” Philadelphia is given “trouble city” status.

A private security firm is given a 10-year contract to provide extra security services to the city. They block cellphone signals and set up landline video portals that monitor communications.

A small cadre of hacker-activists create a workaround that allows residents to send encrypted messages. They also begin disrupting the new drone surveillance system in the city.
