Isolation, you mean on crimes?

Something that has been brought to my attention recently is the lack of newsworthy crime stories in many of our news stations that we have been studying recently. Newsworthy stories are supposed to cover events or topics that affect a large group of people or communities in general. Isolated crime incidents do not fall under this category, yet it is all that these stations seem to report about. For example, in the article http://www.wlky.com/news/Police-Man-charged-with-arson-after-intentionally-setting-his-own-house-on-fire/36167524 , a man is charged with arson after setting his own house on fire. That is an isolated incident that only affects that man and his house, not the community. This makes it unnewsworthy and unacceptable to the public.
