The point of this legislation is to go after the sources who leak classified or sensitive information to other than “corporate media.”
IIRC, Fast & Furious was leaked to Legal Insurrection and another non-corporate news site. (Correct me if I’m wrong, MM.) This bill is intended to prevent non-standard news distribution sites from being able to protect their sources.
The unintended consequences, however, of legally distinguishing traditional corporate media from citizen journalists could be disastrous and used by this administration to target their political opponents as happened with the IRS targeting of Tea Party organizations.
Quite frankly we need more muckrakers....not less.
