> Evidence that someone at some point made an effort to put poison into the apple supply does not directly support that claim. However if credible it is certainly cause to entertain the possibility. Go from the other direction suppose you had millions of cases. By your logic 1 cases is not evidence. Two cases is therefore 0 + 0 = 0 no evidence. Thus by induction 1 million cases is still not evidence. Instead 1 case is weak evidence because each individual cases adds up. For more rigorous analysis see bayesian statistics. Further the article isn’t referring to a single solidity case but instead multiple independent events.
