1. They can cover up 911 because they control US government and media. 2. They can't produce a WMD because Saddam's regime was not controlled by the US. Maybe that's the reason why Saddam and his high ranking officials were all hanged. (because no wants to lie for a not- exist WMD?) I made this very clear in following comment. Read it: Al Qaida (or most other terrrorist group) exists where US intelligence dominates. Al Qaida in US when Bush needs excuse to activate Mid-east war. That was 911 attack. Al Qaida is everywhere in Iraq to bomb innocent civilians when US occupies Iraq. Strange to say, under the Saddam regime, there was no Al Qaida. Al Qaida seems only exist where the regime being controlled by US. So we see no Al qaida in Syria and Iran. But they appear to attack ordinary people when the government either is controlled by US intelligence or supported by US intelligence. That's why you see Al Qaida attacks in US, in Afghanistan, in Pakistan, in Iraq (after it is occupied by US). Because where they are protected by the intelligence, worked as a whip to beat people. When government want money and power, they beat the people with this whip (Al Qaida terror attack) People feel hurt then give up their civil rights and money to the government. DOJ got the Patriot Act. Pentagon got fat budget and Mid-east war.
