bradley manning, for example, is being tried in open court under the draconian 1917 espionage act.

We actually cant have secret trials here, yet, because of that pesky constitution thing.

It does present a bit of a dilemma for the prosecution in that the state may not want to put any of the evidence into the pubic record. Usually a compliant judge grants the prosecution lots of leeway to avoid that, denying defense access entirely, or severely limiting access to evidence and keeping much relevant material out of the public record. Even so the state will frequently plea bargain their way out of any conflicts, or in the cold war days, simply trade one of theirs for one of ours and dispense with the whole thing.

that is far clearer than what I was able to find in a quick search.
