If I remember what I read in the most recent issue of the SPLC's magazine, the incidence of "lone wolf" (one, two people at most) domestic terrorism in the US is on the rise. Hell, the FBI recently caught a pair of guys who damn near built a portable fucking microwave weapon inside an ice cream truck to attack mosques. And, by "damn near," I mean "one component away from having a working prototype." People focus so much on large groups that they forget what a crazy motherfucker (or two) can accomplish when they've got the resources.
