TYPES OF ATTACKS: LaFree, a professor of criminology at the University of Maryland, and his co-author Bianca Bersani, assistant professor of sociology at the University of Massachusetts-Boston, also assessed whether certain counties were more prone to a particular type of terrorist attack.
They found that while a few counties experienced multiple types of terrorist attacks, for most eattacks were motivated by a single ideological type. For example, Lubbock County, Texas, only experienced extreme right-wing terrorism while the Bronx, New York, only experienced extreme left-wing terrorism.
TIME TRENDS: LaFree and Bersani also found time trends in terrorist attacks.
"The 1970s were dominated by extreme left-wing terrorist attacks," Bersani said. "Far left-wing terrorism in the U.S. is almost entirely limited to the 1970s with few events in the 1980s and virtually no events after that."
Ethno-national/separatist terrorism was concentrated in the 1970s and 1980s, religiously motivated attacks occurred predominantly in the 1980s, extreme right-wing terrorism was concentrated in the 1990s and single issue attacks were dispersed across the 1980s, 1990s and 2000s, according to the new report.
To define the ideological motivations, LaFree and Bersani used START's Profiles of Perpetrators of Terrorism - United States (Miller, Smarick and Simone, 2011), which briefly describes ideological motivations as:
Extreme Right-Wing: groups that believe that one's personal and/or national "way of life" is under attack and is either already lost or that the threat is imminent (for some the threat is from a specific ethnic, racial, or religious group), and believe in the need to be prepared for an attack either by participating in paramilitary preparations and training or survivalism. Groups may also be fiercely na
