It would be interesting to see a list of every questionable event that has happened, and the average time it took officials to declare it wasn't terrorism. We are being handled.
Just as telling (or not) would be the list of events that turned out to NOT be terrorism, even though all the keyboard pajamahadeen declared it must be, within seconds of the breaking news.
I don't trust anyone who has some motive, political, entertainment or otherwise, to see every news item fit into their script.
