In a situation like this, you as the leaker have a lot more to lose than whoever you're leaking to.
In that situation, I'm sorry, but the responsibility for protecting your identity is on you. Anonymize the data. Do not leak something that only you would have access to. etc, etc.
Because unless you're leaking to Infowars, you have to expect that a legitimate journalist will present your data to the organization from which you leaked it to, and request comment.
Snoweden did everything right, and it still wasn't good enough.
