How can I find out if my state has a shield law or recognizes a newsgatherer’s privilege?
In 1998, the Reporters Committee for Freedom of the Press published
“Confidential Sources and Information: A Practical Guide to the Reporter’s
Privilege in the Fifty States and D.C.,” in which it set forth a state-by-state
guide to the privilege. This guide is available online.
You can obtain more current information by researching state law in law
libraries or through a number of online databases, including www.findlaw.com.
How have the circuit courts viewed the question of reporters’ privilege?
See this compilation, Branzburg v. Hayes, reporters’ privilege & circuit courts.
