When it comes to fears about a terrorist attack, researchers say domestic extremists who commit violence in the name of their cause – abortion or the environment, for example – account for most of the damage from such incidents in the U.S. reports the Associated Press. Homegrown groups are seven times more likely than overseas groups to commit some kind of violence in the U.S., a panel reported at the annual meeting of the American Association for the Advancement of Science.
“The typical ‘terrorist’ is an alienated guy, usually a young male,” said Brian Forst of American University in Washington. “They take comfort in like-minded souls and develop an idea they think will make a splash,” he said. Kelly Damphousse of the University of Oklahoma said right-wing extremists spend the most time planning before committing a violent act – some 480 “events.” On a smaller scale are environmental activists who commit violence. On average, it is just 59 preparatory activities. Tuesday is the most common day for an attack. David Caspi of the John Jay College of Criminal Justice said domestic extremist groups tend to fall into three categories – political, religious, and youth culture.
