What Sashimi said. They have a pretty bad record on burning sources, Winner was one of the more high profile but there were a string of them in fairly rapid succession.
Also as they said, on the plus side Liliana Segura and Jordan Smmith are real reporters and constantly take on power in the context of the US "justice" system and wrongful convictions. Their work is some of the best stuff they publish and they have been the driving force behind exposing and helping to overturn several major wrongful convictions.
