Global warming and the integrity of science.
Science requires the free flow of research and ideas. The Bush administration ignored the science on global warming and even tried to prohibit publication of a study on the safety and security of the milk supply. Eventually the study was published.

  Safety at chemical plants.
Around the U.S. sit more than 120 chemical plants, each of which could injure or kill over a million people. But that's about all we know about how these facilities threaten our communities. Even before 9/11, Congress passed a law limiting information available to the public about the impacts of potential accidents or attacks on chemical plants around the countries. Although EPA collects “worst case scenarios” from chemical plants, the public can get the data only through reading rooms on a limited basis. And all this secrecy has bought only inaction: More than 4 years after 9/11, Congress has failed to mandate standards for security at chemical facilities.

  Katrina, secrecy, & government accountability
Transparency is critical for the public to hold its government accountable for its actions. Congressional investigations into the government's failures to prepare and respond to Hurricane Katrina have been stymied by refusals to turn over documents and a failure to disclose how agencies and contractors spend taxpayer dollars to aid the clean up and recovery.
