Militia on the streets of New York City?

A police shooting of a young black couple (the Martins) leads to protests that escalate into riots. The riots culminate with the deaths of a white couple: renowned civil rights attorneys, Stanley and Theresa Milgram. The murder was broadcast live by a local news helicopter. The media plays the clip incessantly; unaware of the trauma it's causing the nation.

A small militia group feels this is their calling and drive down to New York. A bloodbath ensues. The world watches as NYC spins out of control. The National Guard has been called in. And the mayor seems to think that the only way the violence can be quelled, is for the Milgrams' two sons to come out and call for calm....but they won't.
