Hesiod corrects the firefighter story. They did not decide to boycott the 9-11 tribute, just considered it. They are pissed.
He also points to Jeanne D'Arc's realization that the BBC has reported that the recent lawsuit by 9-11 victims' families also "targets the US government for failing to pursue the Saudis thoroughly enough because of oil interests."
This was left off every news report I heard, though it may have appeared in print versions.
