Is there a cover up dealing with the German co-pilot who crash the plane?

Is there a cover up dealing with the German co-pilot who crash the plane? I don't know but story of mental illness causing him to crash plane is hard to believe. In West we don't like to point finger at
Muslim crazies, which makes you think who are crazy ones? These people want kill us yet we afaid to call them out why? Even the President of the United States doesn't want to condemn these Muslim crazies for terror they cause. What is wrong with us? If we don't combative this evil in most extreme way Western Civilization may not survive!
