US media self-censorship
""The same dynamic drives most of these acts of US media self-censorship. It has nothing to do with legitimate claims of national security. Indeed, none of these facts - once they were finally reported - ultimately resulted in any harm. Instead, it has everything to do with obeying government dictates; shielding high-level government officials from embarrassing revelations; protecting even the most extreme government deceit and illegality; and keeping the domestic population of the US (their readers) ignorant of the vital acts in which their own government is engaged.""
