Sadly, a lot of the things most worth hearing about in the world are quite dark, and telling the truth about them without perfect evidence would get you sued by vastly powerful enemies.
And even bringing perfect evidence you might be liable to 'have an accident', or get smeared to high hell. Whistleblowers and investigate journalists have had a pretty rough time of it this past few decades.
Like, just look at what happened with Wikileaks, or Snowden, or Boeing, or the Panama Papers, or the FBI agents mentioned as having been murdered in the latest Epstein drop, or the 234 journalists murdered by Israel the past couple years [0] (many with their entire families)... Etc etc.
