While  federal government scientists play a critical role in protecting our health,  safety and environment, many report that they are often discouraged from  sharing their scientific research and analysis with the media and the public.  In fact, a recent Union of Concerned Scientists investigation found that the  media policies and practices of some federal agencies effectively censor  scientists, impeding their ability to discuss their work with their peers and  with interested journalists who convey research findings to the public.
 Other  federal agencies—like NASA—have changed their policies to allow their  scientists far greater freedom in meeting their public service missions,  demonstrating that it is possible for the government to do better. 
Federal  scientists must feel free to speak out about research findings that impact our  lives. Please urge federal agency leaders to improve their agencies' media  policies.
Subject: Allow Scientists to Speak Freely With the Public
Dear [Agency Official],
A recent investigation conducted by the Union of Concerned Scientists found that your agency could improve its communication between agency scientists and the press. Please create a forward-thinking media policy that encourages open communication between scientists, the media, policy makers and the public.

Federal scientists should be able to alert the public when their research indicates a potential public health, safety or environmental hazard. Unfortunately, there have been many recent documented cases in which scientists at federal agencies have been censored and the media stymied in their attempts to access government scientific information.
In order to meet your public service mission, your agency should allow scientists to more effectively communicate about their scientific research and expertise. A model media policy can be found here:
