I'm sorry, what? :D
See also the uniform blackouts of some of the most important details surrounding many other events, such as: The USS Liberty. TWA flight 800. the hannibal directive. Bobby Kennedy's assassination. Flight MH17. The venona papers. The deaths of 6 of America's top political figures at the end of WW2 (W. Wilkie, G. Patton, H. Hopkins, H.D. White, L. Duggan, J Forrestal). Should I keep going?
The point is: regardless of what you think about any of these events, it's indisputable that many of the most relevant details have been uniformly ignored by every mainstream outlet.
The book "Encountering American Pravda" by Ron Unz will give you many more examples with abundant sources, if that's your thing.
