Matthew Bracken - The Enemies Trilogy (#1 -3)

#1. Enemies Foreign And Domestic: BULLETS RAIN DOWN UPON A PACKED FOOTBALL STADIUM, killing dozens, and triggering a panic stampede which leads to a thousand more deaths. A police marksman kills the sniper, a mentally unbalanced Desert Storm veteran holding a smoking assault rifle. It's an open and shut case, or so America is led to believe.
In the aftermath of the stadium massacre, an outraged public demands an end to the threat posed by assault rifles, and Congress passes emergency legislation banning their private possession. American gun owners have one week to turn in their semi-automatic rifles, or face mandatory five year federal prison terms.
Jimmy Shifflett, the alleged stadium sniper, is linked to a shadowy "gun club" in southeastern Virginia, which the FBI believes is a cover for a secret right wing militia terror group. Those who knew Shifflett the best don't believe he was a member of any militia, or that he was guilty of the horrific mass murder.
But if he didn't fire the "assault rifle" into the stadium, who did, and why? A small band of Virginians, thrown together by fate, is forced to undertake a desperate odyssey through a minefield of government blackmail, official deception and covert death squads, to discover the truth behind the stadium massacre, and save their own lives.

#2. Domestic Enemies: The Reconquista: it is the second one in the series of Enemies Trilogy and A novel about the deconstruction of the American national identity, and the loss of the Southwest.

#3. Foreign Enemies and Traitors: "Foreign Enemies And Traitors" is set in the near future in an America that is creeping steadily toward socialist tyranny, in the midst of the second Great Depression. A year after earthquakes have devastated the Tennessee Valley, survivors are resisting demands by the federal government to relocate to FEMA refugee centres. United States National Guard units have proven ineffective at forcing these survivors out of the earthquake-damaged regions, due to their reluctance to employ deadly force against fellow Americans. As a result, the president has invited so-called foreign peacekeeping battalions to do the work of forcibly relocating the holdouts. The novel follows a small group of determined survivors in their resistance to the foreign enemies, and the American traitors who are their allies.
