"While a variety of think tanks and journalistic organizations have compiled data that capture fragments of the domestic terrorism picture —Islamist attacks (The Heritage Foundation), deadly domestic terror attacks (the think tank New America), attacks on abortion clinics (the National Abortion Federation) and far-right plots and attacks (the Southern Poverty Law Center) — The Investigative Fund database is the only one that gathers incidents that span the full range of ideologies and that includes both plots and attacks and both federal and local prosecutions. It also catalogues each incident according to a diverse range of variables, such as target, ideology, movement affiliation, sentence, and whether federal charges or terrorism charges were filed. (See our methodology here.) The database vividly illustrates the ways in which Islamist incidents have received disproportionate attention from federal law enforcement. While a majority of the incidents were perpetrated by right-wing extremists (57 percent), the database indicates that federal law enforcement agencies focused their energies on pre-empting and prosecuting Islamist attacks, which constituted 31 percent of all incidents, a finding confirmed by counterterror experts."
