The era of investigative journalism in newsprint was the 1970s. Reporters are now not only fired, as RFK Jnr. said, but are frequently killed in war zones. Instead of investigative journalists now we have "Truthers" who spin speculative conspiracy theory fairy stories and muddy the water for people who want to know the inside story.
On the plus side we have the internet, which allows for spread of news and debate to a wider extent than ever before. The difficulty is quality control - a mass of information but no editorial scrutiny.
