How much should we worry about Islamic terrorism? How much should we worry about other kinds?
There’s no exact right answer to this question. Who is out there in dark places plotting murder most foul? We can only guess, using imperfect information. Of course, there’s “imperfect” and then there’s downright distorted.
The New York Times highlighted one data set recently, in an article headlined “Homegrown Extremists Tied to Deadlier Toll Than Jihadists in U.S. Since 9/11.” “Since Sept. 11, 2001,” the article says, “nearly twice as many people have been killed by white supremacists, antigovernment fanatics and other non-Muslim extremists than by radical Muslims: 48 have been killed by extremists who are not Muslim, including the recent mass killing in Charleston, S.C., compared with 26 by self-proclaimed jihadists, according to a count by New America, a Washington research center.” The article goes on to cite a nationwide survey of police and sheriffs departments, noting that “74 percent listed antigovernment violence, while 39 percent listed ‘Al Qaeda-inspired’ violence, according to the researchers.” Well, I guess that settles that, then.
Ah, no. You’ve been reading this column too long to believe that. Statistics are useful, but fragile. How you handle them makes a big difference.
