Why is leaking classified information special to the point where someone even accused of that crime is unworthy of help no matter the circumstances?
More generally, just because someone is indisputably guilty of violating some statute doesn't mean they deserve the prescribed punishment. You're taking a legal conclusion and imputing some sort of moral authority to it. The law often requires outcomes that are arguably immoral. Sometimes this provides the motivation to change the law. Other times, judges ignore the law. And sometimes, the government does terrible things because nobody does anything to stop it. It seems ridiculous to argue that someone who is arguably being punished for doing the right thing should just stand there and take whatever the law metes out.
