The Myth of the "Lone Terrorist"

Former FBI agent Mike German writes about the swamps which breed terrorism in today's Washington Post opinion column:Behind the Lone Terrorist, a Pack Mentality:

Bringing to justice everyone directly responsible for acts of violence is important, but unmasking the full conspiracy is even more important from the standpoint of preventing terrorism. Lone extremists pose a challenge for law enforcement because they are difficult to predict. It's like searching every haystack for a needle. Perhaps we'd have better luck if we paid more attention to the needle factories. This is especially true now that militant Islamic terrorist groups like al Qaeda are adopting the model of leaderless resistance that our homegrown terrorists mastered so well.
