The Islamic State’s suspected inroads into America by Adam Goldman , Jia Lynn Yang, and John Muyskens.
From the post:
Federal prosecutors have charged 84 men and women around the country in connection with the Islamic State. So far, 32 have been convicted. Men outnumber women in those cases by about 7 to 1. The average age of the individuals is 27. One is a minor. The FBI says that, in a handful of cases, it has disrupted plots targeting U.S. military or law enforcement personnel.
The post breaks down proceedings by state and lists each person separately, along with the source of the information.
If you are looking for a small but significant data set on terrorism, I think this is the place.
If you develop further information on these cases, repay the original authors by sharing your discoveries.
