How come you've never heard of this?

Because the perpetrators aren't Muslim. BushCo needs to keep a certain critical level of anti-Arab sentiment stoked so it can prolong its illegal war for as long as possible. The "War on Terror" needs nice, neat polarized "good guys" and "bad guys." This leaves no room whatsoever for real terrorists with real explosives if they happen to be home-grown white boys.

No, "terrorists" are from the Middle East and worship Allah. Everyone knows that.
