The Congressional Research Service, Congress' nonpartisan research arm, has published a report on domestic jihadism, along the same lines (though at greater length) as our recent examination of the same topic. CRS' report contains more detail on individual cases.

On a related topic, the growth of anti-Muslim sentiment which - some say - spurs alienation among young Muslims, perhaps predisposing them to jihadist sympathies, is documented in a new interactive map published by the Pew Forum on Religion & Public Life, also nonpartisan.
