A lone wolf, lone-wolf terrorist, or lone actor, is someone who prepares and commits violent acts alone, outside of any command structure and without material assistance from any group. He or she may be influenced or motivated by the ideology and beliefs of an external group and may act in support of such a group. In its original sense, a "lone wolf" is an animal or person that generally lives or spends time alone instead of with a group.
Observers note the attacks are a relatively rare type of terrorist attack but have been increasing in number, and that it is sometimes difficult to tell whether an actor has received outside help and what appears to be a lone wolf attack may actually have been carefully orchestrated from outside.
Origins of the termEdit
The term "lone wolf" was popularized by white supremacists Alex Curtis and Tom Metzger in the 1990s. Metzger advocated individual or small-cell underground activity, as opposed to above-ground membership organizations, envisaging "warriors acting alone or in small groups who attacked the government or other targets in 'daily, anonymous acts.'"
Terrorism expert Brian Michael Jenkins of the RAND Corporation prefers the term stray dog to lone wolf. According to Jenkins, most individuals involved in such attacks "skulk about, sniffing at violence, vocally aggressive but skittish without backup". Though these individuals seem to be acting alone, there are often ties between lone wolves and terrorist organisations for example, terrorist backed online content. 
The term "lone wolf" is used by US law enforcement agencies and the media to refer to individuals undertaking violent acts of terrorism outside a command structure. The FBI and San Diego Police's investigation into the activities of a self-professed white supremacist, Alex Curtis, was named Operation Lone Wolf, "largely due to Curtis' encouragement of other white supremacists to follow what Curtis refers to as 'lone wolf' activism".
The term lone wolf is used to distinguish terrorist actions carried out by individuals from those coordinated by large groups. Terrorist attacks that are carried out by small cells are not classified as lone wolf attacks. Lone wolf attacks are far more rare than attacks carried out by groups. Since 1940, there have only been around 100 successful lone wolf attacks in the United States. The number of attacks is increasing, however, and has grown each year since 2000. Lone wolves generally come from different demographics than far right attackers as well. As compared to those on the far right, lone wolf attackers who become inspired by al-Qaeda and ISIS tend to be younger and better educated. According to studies, lone wolves have more in common with mass murderers than they do with members of the organized terrorist groups that often inspire them.
While the lone wolf acts to advance the ideological or philosophical beliefs of an extremist group, they act on their own, without any outside command or direction. The lone wolf's tactics and methods are conceived and directed solely on their own; in many cases, such as the tactics described by Curtis, the lone wolf never has personal contact with the group they identify with. As such, it is considerably more difficult for counter-terrorism officials to gather intelligence on lone wolves, since they may not come into contact with routine counter-terrorist surveillance.
A 2013 analysis by Sarah Teich, a research assistant at the International Institute for Counter-Terrorism, found five emerging trends in Islamist lone wolf terrorism in North America and western Europe between 1990 and 2013:
- An increase in the number of countries targeted by lone wolves from the 1990s to the 2000s.
- An increase in the number of people injured and killed by lone wolves.
- Increased effectiveness of law enforcement and counter-terrorism.
- Consistency in the distribution of attacks by "actor types" (loners, lone wolves, and lone wolf packs).
- An increase in the number of attacks against military personnel.
In the United States, lone wolves may present a greater threat than organized groups, and terrorists have not been limited to Muslims. According to the Christian Science Monitor, "With the exception of the attacks on the World Trade Center, experts say the major terrorist attacks in the United States have been perpetrated by deranged individuals who were sympathetic to a larger cause – from Oklahoma City bomber Timothy McVeigh to the Washington area sniper John Allen Muhammad," both native-born Americans.
Some groups actively advocate lone wolf actions. Anti-abortion militant terrorist group The Army of God uses "leaderless resistance" as its organizing principle. According to The New York Times, in news analysis of the Boston Marathon bombings, the Al-Qaeda activist Samir Khan, publishing in Inspire, advocated individual terrorist actions directed at Americans and published detailed recipes online.
Lone wolf terrorists are frequently thought to only be Muslims, however, this is not always the case. Lone wolf terrorists may sympathize with and consider themselves part of larger groups, but they are not truly a part of them. Often, the attacks are attributed to people who have a mixture of political and personal grievances. The attackers can have no actual affiliation to the group that claims them, but instead become radicalized online and through external media outlets.
A large number of terrorists determined by authorities to have been lone wolf attacks inspired by ISIS and/or its ideology, were later found to have been recruited, trained and directed remotely by ISIL to carry out the attacks.
Mental health factorsEdit
Lone wolf terrorists are highly likely to be afflicted by a mental illness. Studies have found that more than 40% of lone wolf terrorists have been diagnosed at some point in their life with a mental illness. This puts lone wolves as being 13.5 times more likely to suffer from a mental illness than a member of an organized terrorist group, such as al-Qaeda or ISIS.
Mental health challenges are thought to make some individuals among the many who suffer from certain “psychological disturbances,” vulnerable to being inspired by extremist ideologies to commit acts of lone wolf terrorism.

- On 28 November 2016, in the Ohio State University attack, a car ramming attack and mass stabbing occurred at 9:52 a.m. EST at Ohio State University (OSU)'s Watts Hall in Columbus, Ohio. The attacker, Somali refugee Abdul Razak Ali Artan, was shot and killed by the first responding OSU police officer, and 11 people were hospitalized for injuries. According to authorities, Artan was inspired by terrorist propaganda from the Islamic State and radical Muslim cleric Anwar al-Awlaki.
- On 1 October 2017, Stephen Paddock, a 64-year-old U.S. citizen, opened fire with an automatic weapon from the 32nd floor of the Mandalay Bay hotel in Las Vegas, Nevada, on a crowd at the Route 91 Harvest country music festival, which was taking place near the hotel. At least 59 people were killed and more than 500 wounded from gunshots and other injuries. Paddock, who killed himself, was described by police as a lone wolf, although, as of yet, the police have refrained from describing the incident as an act of terrorism.
- On 20 October 2014, in the 2014 Saint-Jean-sur-Richelieu ramming attack, the radicalized Saint-Jean-sur-Richelieu citizen Abu Ibrahim AlCanadi ran a soldier down and shot another. Couture-Rouleau was, in the aftermath, shot dead by an officer of the Sûreté du Québec.
- On 22 October 2014, Michael Zehaf-Bibeau opened fire at the National War Memorial. One soldier was shot. The suspect ran to the Parliament of Canada. The suspect was then engaged in a shoot out with security and police forces.
- On 29 January 2017 in the Quebec City mosque shooting, Alexandre Bissonnette, a Political science student at the University of Laval, opened fire in the Islamic Cultural Centre of Quebec City and killed six worshipers.
- On 15 December 2014, a hostage crisis in the Lindt Café in Martin Place, Sydney ended with three deaths, including the suspect Man Haron Monis. There is doubt as to whether or not Monis fit the definition of a lone wolf terrorist. Queensland University of Technology criminologist Associate Professor Mark Lauchs said it was important the siege wasn't elevated to a "terrorist attack" as such. Associate Professor Lauchs said Monis was simply a deranged person running a hostage situation: "This incident was not about religion and neither was it a terrorist attack, but given that perception by the paraphernalia Monis used." The Australian Prime Minister Tony Abbott said, "[Man Haron Monis] had a long history of violent crime, infatuation with extremism and mental instability. As the siege unfolded yesterday, he sought to cloak his actions with the symbolism of the ISIL death cult." Former counter-terrorism adviser to the White House Richard Clarke said, "I don't think this was a lone wolf terrorist, I don't think this was a terrorist at all, I think this was someone who was committing suicide by police as a lot of people with mental problems do, and now, if they say they're a terrorist, if they say they're somehow associated with ISIS or Al Qaeda, it becomes a major event that shuts down the city and gets international attention. This was a person with a mental problem who tried to gain attention and succeeded, tried to shut down the city and succeeded, merely by putting up a flag that was something like the flag of ISIS."
