Construction of Representations in the News

They tell the audience how many people were killed and therefore sets its importance in the news. It is bad news so has a higher news value than any good news. Also, because it is the United States and it is culturally similar to the United Kingdom, it could also be spoken widely about within the UK and will probably be shown in the news. If the news is fairly new and is aired before other similar news channels then it will get noticed faster and possibly have more viewers. It isn't odd anymore to hear of shootings etc in America. However, whenever one does happen it is still quite surprising around the  amount of people who are killed or shot innocently because of nothing. Stories like this involve the readers emotionally as they can imagine how it must feel for the families of the victims to lose somebody close to their heart.
