Who is allowed to decide which secrets should or should not be made public? If your answer is "the government", then every cover up will never be revealed, and the government will answer to no one. If your answer is "journalists", then you have the status-quo in any functioning democracy. And when it actually moves into sedition territory, that's what an independent court system is for. Unfortunately, once things devolve into a two-party system, it becomes ever increasingly difficult to keep the various branches independent.
