Whistle-blowing reveals not just acute misdeeds, but chronic and longstanding patterns of misconduct. For example, Edward Snowden’s bombshell release of more than 200,000 documents revealed questionable government surveillance programs that existed for years. Miami Dolphins player Jonathan Martin withdrew from play, alleging more than a year of emotional abuse from teammate Richie Incognito. These high-profile cases are just a few examples of what happens in organizations large and small every day.
