1) media is about money. 2) money is acquired by advertising or subscription. 3) ads or subscriptions need people to read/view and to continue to do that. 4) the best way to influence someone to do that is through emotions. 4) news articles are selected or spun in a way that instills/increases emotions in a targeted audience. 5) if someone in Tibet gets hit by a truck then it is unlikely to produce a reaction to someone in NY. 6) if the demographically relevant person is hit by a truck related to an already unfavorable organization outside an apartment building in NY then that will have a much more likely emotional response and so will be that much more likely to be reported. this applies to 99% of media, regardless of whether it is politics, crime or sports. tl;dr = money.
