Any bit of classified information can be reasonably considered in the interest of someone in the public.
Public interest can only mitigate the illegality of what you're doing, it doesn't just magically make the act illegal.

False dichotomy.
If you want to rob a bank, and you come and ask me to be the getaway driver, we're both going to hang. It doesn't matter who had the idea for the crime, what matters is that he materially assisted in carrying it out.
Now, if you robbed a bank, and just dropped a million dollars on my porch, that would be a different story. That's the defense journalists use when they receive illegally obtained information.
