It is certainly not the business of a private to determine what type of classified information should or should not be distributed.
A long time ago, it was expected that all military personnel should follow orders, rules and regulations, and that they would not be held accountable for their actions while doing so.
Then, as a species, we grew up a little, and a number of events including Nuremberg helped us to realise that this was not a healthy attitude.
Now, in 2012 many people still believe it is "right" to lie about and cover up the killing of innocent people. I hope, as a species, we will continue to grow and to understand that this is unacceptable. When it comes to the murder of non-military personnel, being part of such a cover-up should be regarded as an abuse of human rights (it is, after all, a conspiracy to hide a crime against humanity) and military personnel *should* have whistleblower rights, in a limited range of circumstances.
