He is merely wrong by law, not by morality. If I might remind the slashdot crowd: authority is doing what you are told, regardless of what is right; morality is doing what is right, regardless of what you are told.
Being an independent thinker, I side with morality, and therefore he is a hero.
To quote the excellent Rap News 19: Whistleblower:
Some praise these acts as heroic, worthy of mimicking
Others condemn them as illegal and prohibited
But, can't both be equally applicative?
To be good humans we're sometimes
called upon to be bad citizens.
Some nations were even born by
breaking laws of the tyrannous.
Do you support heroes from days of yore
who in order to cause reforms disobeyed the law?
Then what about those in the present
who heed the same call?
