I agree, we should not shift the blame from the terroristic traitors that were involved in these murders, theft, destruction of property, insurance fraud, formation of unconstitutional oversight and illegit actions against other countries in our name.
Bush, Cheney, Silverstein, CIA (bldg 7) and the whole gang of domestic terrorist that were involved should not go unpunished.
