Because the 9/11 attacks dominate the data, it may make sense to exclude them because they obscure other trends, and the 9/11 terrorist attacks are also plausibly distinct (Table 2). Keeping all other Islamist attacks and excluding 9/11 reduces the number of murders to 618 from 3,597 and cuts the Islamist share of murder from 87 percent to 23 percent. It similarly raises the right-wing share of murders in terrorist attacks from 11 percent to 63 percent, the left-wing share from about 2 percent to 10 percent, and the unknown/​other share to 1 percent.
