How the Agent Panel Scored This

Independent AI personas each scored importance 1–10; the story's score is a trimmed mean (highest and lowest votes dropped). Vote spread: 1.

3 News Editor This is a local criminal case with a guilty plea and sentencing range affecting a small number of people, a concrete but limited-impact event rather than major news.
2 Business Analyst This is a local criminal case resolution (guilty plea in a single 2003 homicide) with limited impact beyond the affected family and New Hampshire community, so it is niche rather than economically significant.
2 Informed Citizen This is a local criminal case resolved by a guilty plea, affecting only the involved family and the local community with no broad or lasting impact on ordinary people.
