Source: Investigate West
I found an investigative report about Boeing and how it managed to manipulate the government of Washington State into not passing pollution rules that would have protected Native Americans from polluted fish.
The story gathered a wide range of sources for its reporting. Many of these were not public documents but included emails between legislators and even emails from private company officials. The reporters likely gathered these sources either form a leak provided to them or by seeking out people close to the sources who had access to them.
Throughout the story, the reporters link to the documents digitized and hosted on their sites when they reference material from them. This allows readers to see what exactly is in the documents without the reporters needing to spell it all out in their article. This improves the flow of the writing while also including all the behind-the-scenes information.
This feature is just one in a series of stories about businesses triumphing over public health. Links to these stories, organised in an orderly sequence, is displayed on the right side bar of the story. This lets readers jump to them easily.
