If you want to get upset about a cover up why not get upset over the 21 to 25000 American soldiers that Russia kept as prisoners after WWII? Eisenhower apparently wrote off the soldiers as to difficult to recover from Russia. American politics covered it up. Russia used them like the other Siberian prisoners, any way they wanted. Saw a documentary several years ago on this subject. Do some googling and it seems that it's been known about and covered up since the end of the war.
