Yes, it is a good question. Minor fine tune on your explanation: "on how it will affect others". Take local theater owner, Bill Miller. Had about a dozen or so theaters. He was murdered in his office. It affected a large majority of people: his patrons, his employees, friends, associates, etc. It was considered a murder because he was a businessman. Still unsolved. All his theaters havecshut down. Two drive ins now house Wal-Mart stores.
I'd say the figure would have to be elected official or prominent SJW. Huey Long would be an elected official and MLK would be an SJW. Madeline O'Hare and her family was murder because the force behind it was theft.
Not sure what Jimmy Hoffa would have been.
