I want to know the answer to the following question:
What did Harff define as "short-lived outbursts by mobs...?"
All the background I'm provided with is that "Daniel D. Polsby and Don B. Kates, Jr. state that "... we follow Harff's distinction between genocides and 'pogroms,' which she describes as 'short-lived outbursts by mobs, which, although often condoned by authorities, rarely persist.'". Is that enough to answer the question?
