The current state of whistleblowing prosecutions under the Espionage Act makes a truly fair trial wholly unavailable to an American who has exposed classified wrongdoing. Legal scholars have strongly argued that the US supreme court – which has never yet addressed the constitutionality of applying the Espionage Act to leaks to the American public – should find the use of it overbroad and unconstitutional in the absence of a public interest defense. The Espionage Act, as applied to whistleblowers, violates the First Amendment, is what they're saying.
As I know from my own case, even Snowden's own testimony on the stand would be gagged by government objections and the (arguably unconstitutional) nature of his charges. That was my own experience in court, as the first American to be prosecuted under the Espionage Act – or any other statute – for giving information to the American people.
I had looked forward to offering a fuller account in my trial than I had given previously to any journalist – any Glenn Greenwald or Brian Williams of my time – as to the considerations that led me to copy and distribute thousands of pages of top-secret documents. I had saved many details until I could present them on the stand, under oath, just as a young John Kerry had delivered his strongest lines in sworn testimony.
But when I finally heard my lawyer ask the prearranged question in direct examination – Why did you copy the Pentagon Papers? – I was silenced before I could begin to answer. The government prosecutor objected – irrelevant – and the judge sustained. My lawyer, exasperated, said he "had never heard of a case where a defendant was not permitted to tell the jury why he did what he did." The judge responded: well, you're hearing one now.
