Another Foxlike website - the second link, at least.
While I only skimmed the McCarthy report [and BTW, he DID cause a blacklist of many talented Hollywood writers & directors, among them my beloved Ring Lardner, and with the help of then Screen Actors Guild President Ronald Reagan, who gave up the names of everyone he had ever seen discussing Marxism], my eye was caught by the headline "Air Force tells servicemen not to read stories about NSA data collection". That seems outrageous - we don't like censorship in America! so I read that one.
And gollygee, what does the actual order say? It says that downloading the classified documents found on sites such as the Guardian [original source], may be considered illegal.
It did not prohibit servicepeople from reading articles on the subject.
I'm doubting whether it's 100% accurate on the subject of McCarthy, as well.
