In the last six years, incidents of domestic terrorism in the United States have been overwhelmingly carried out by solitary “lone wolves” or leaderless groups of just two people. The Southern Poverty Law Center’s study of the nature of these attacks is based on the following 63 incidents, which occurred between April 1, 2009, and Feb. 1, 2015. The list includes both terrorist attacks and foiled terrorist plots, as well as unplanned situations, such as traffic stops, where extremists were confronted by law enforcement officials and reacted with major violence. The ideologies driving the homegrown extremists in each incident are divided into two broad categories: “antigovernment,” meaning the perpetrators see the federal government as their chief enemy and generally subscribe to the tenets of the so-called “Patriot” movement; and “hate,” which encompasses hatred based on race, religion, gender, and sexual orientation, among others (jihadist attacks and anti-abortion violence are included in this category). An asterisk in the “outcome” field, which lists the number of people killed, indicates that one or more assailants died during the terrorist incident. If the incident is listed as a “group” attack, there were at least two assailants involved. The “perpetrator” field includes a few cases where the defendant has been accused, but not convicted, of a crime. The cases that mention “sovereign citizens” refer to people with radical antigovernment views who believe most laws don’t apply to them.

RICHARD ANDREW POPLAWSKI shoots and kills three Pittsburgh police officers responding to a call about a domestic dispute with his mother, who wanted to kick him out of her house. Poplawski believed that an attack on gun rights was imminent and that U.S. troops would be used against U.S. citizens; he also thought a secret cabal of Jews ran the United States. Poplawski was heavily influenced by radio radical Alex Jones, many of whose conspiracy theories he believed.

SCOTT ROEDER, an anti-abortion extremist who was involved with the antigovernment “freemen” movement in the 1990s, shoots to death Kansas abortion provider George Tiller as the doctor is serving as an usher in his Wichita church. Adherents of the freemen movement describe themselves as sovereign citizens not subject to federal and other laws, and often issue their own vehicle license plates. It was one of those unauthorized homemade plates that led Topeka police to stop Roeder in 1996, when a search of his trunk revealed a pound of gunpowder, a 9-volt bat- 18 southern poverty law center tery wired to a switch, blasting caps and ammunition. A prosecutor in that case called Roeder a “substantial threat to public safety,” but his conviction in that case is overturned later. In 2010, Roeder is sentenced to life in prison for the Tiller murder.

JAMES VON BRUNN, a longtime neo-Nazi, shoots to death security guard Stephen Johns at the U.S. Holocaust Memorial Museum, but is critically wounded by other officers as he tries to storm into the facility. Von Brunn had a long history in the white supremacist movement. In the early 1970s, he worked at the Holocaust-denying Noontide Press and in subsequent decades he came to know many of the key leaders of the radial right. In 1981, von Brunn used a sawed-off shotgun to attempt unsuccessfully to kidnap members of the Federal Reserve Board in Washington, and served six years in prison as a result. A search of Von Brunn’s car after the museum attack turns up a list of apparent targets including the White House, the Capitol, the National Cathedral and The Washington Post. A note left there by von Brunn reads: “You want my weapons; this how you’ll get them … the Holocaust is a lie … Obama was created by Jews. Obama does what his Jew owners tell him to do. Jews captured America’s money. Jews control the mass media.” Von Brunn is charged with murdering Johns but dies in 2010 while awaiting trial.

FBI agents arrest RICHARD SCHMIDT, the owner of a sporting goods store in Bowling Green, for trafficking in counterfeit goods and discover a cache of 18 weapons in his home and store, including AR-15 assault rifles, 9 mm and Sig Sauer pistols and shotguns, and more than 40,000 rounds of ammunition. Schmidt is unable to own the weapons legally because he is a felon who served 13 years for murdering a Latino man and wounding two others in a 1989 traffic dispute. Officials also find evidence of Schmidt’s neo-Nazi views, including video and Nazi paraphernalia, and the Anti-Defamation League identifies him as a longtime member of the neo-Nazi National Alliance. Authorities also discover a notebook they say Schmidt was using to track Detroit-area Jewish and African-American leaders, apparently as a prelude to some kind of attack. Schmidt is indicted in Toledo in January 2013 on three federal counts of possessing illegal firearms, body armor and ammunition, and one count of trafficking in counterfeit goods. He pleads guilty in July of that year to violating federal firearms laws and is later sentenced to nearly six years in prison.

GLENDON SCOTT CRAWFORD, 49, and ERIC J. FEIGHT are arrested at their homes in upstate New York after a year-long investigation and charged with conspiracy to provide material support to terrorists for use of a weapon of mass destruction.

Crawford is a member of the United Northern and Southern Knights of the Ku Klux Klan and an industrial mechanic with General Electric; Feight is an outside contractor for the company with engineering skills. Officials say the two men, who call themselves “The Guild,” are well on the way to building a truck-borne radiation weapon that can be turned on remotely and that they hoped to see used in the mass murder of Muslims and others. Crawford allegedly refers to the device as “Hiroshima on a light switch.” The men are arrested after allegedly seeking funding for the weapon from Jewish groups and the Loyal White Knights of the Ku Klux Klan without success. In 2014, Crawford is indicted for conspiring to use a weapon of mass destruction and related charges, while his alleged accomplice is reportedly in talks about a plea agreement that would involve testifying against Crawford.

The two are charged with felony conspiracy to commit murder, conspiracy to commit kidnapping and attempted kidnapping. Newman pleads guilty in December 2013 to conspiracy to commit false imprisonment, a misdemeanor, and is sentenced to a year of probation and ordered to have no contact with Brutsche. Brutsche, who renounces sovereign citizen ideology during court proceedings, pleads guilty in February 2014 to conspiracy to kidnap police officers and receives five years of probation. In a separate case involving failure to register as a sex offender, he receives 188 days in jail in addition to time served.
