At face value it doesn't seem so crazy to charge him for this. I mean it is committing a crime by proxy as opposed to passively obtaining information from a source (the latter of which journalists should be protected for).

If I give tools and a robbery checklist to someone and tell them to rob a bank, surely I'm still able to be charged and probably for a higher crime right? At least that's how these charges seem to me. I guess I don't see how it's invalid.

I do however see how this could set a dangerous precedent should the courts allow loose interpretation of the outcome to mean "reporting leaked information is illegal"
