I still don't get what you think is "newsworthy", or what "should" be reported on.

Why is homicide inherently more newsworthy than "people get heart attacks"? It completely depends on how much homicide is happening, how many heart attacks are happening, and what we as a society think is reasonable for either fatality. Given how few people are dying with homicides, how many people are dying from a preventable disease -- which is what the main article here says -- I think there can absolutely more attention put on the preventable disease. Particularly at a moment in time when funding for healthcare by the government is being dramatically reduced.
