James Holmes, the Aurora, Colorado mass murderer, hasn't gone to trial yet, but his attorneys are already reaching out to the Supreme Court. Why?
The reporter's privilege (or "shield") and choice of law issues.
Shortly after the shooting, an unknown source(s) leaked word of a notebook, sent to a University of Colorado psychiatrist, that contained drawings and plans for the movie theater shooting. The notebook was under a gag order. Holmes' attorneys sought to compel testimony of reporter Jana Winter about her sources, but a New York court stepped in and applied that state's reporter's privilege.
The shooting, the notebook, the gag order, and the disclosure all happened in Colorado.
