Mike, appreciate the link on the Wall St attack (I wasn't aware of that one).

As you know not all lone wolf attacks are terrorist attacks and it is important to point out the difference. If the attack doesn't have a political agenda then it isn't terrorism, even if it terrorifies those exposed to it. While the numerous school shootings in our country and workers going postal are equally tragic regardless of motivation they are not generally terrorism. I think the attack on the Bath School was a guy that was pushed over the edge and went postal on his family and the school (local gov).

Timmy McVeigh wasn't a lone wolf, but supposedly he was part of a very small cell and his attack on Okalahoma City was clearly terrorism (politically motivated). Some lone wolf terrorists in the U.S. were the unibomber and MAJ Hason at Ft Hood. I agree that lone wolfs are probably harder to detect, and therefore their attacks may be more likely to succeed, but not necessarily be overly effective.
