As a former librarian, I know that selection is the key to a collection. Banning or promoting a point of view starts in the back room where the purchasing decisions are made. Public library librarians are 123:1 liberal to conservative, so that determines what is purchased, which determines what people read, which determines what they believe. Same with the news. How news sources differ just by selection of story was evident with these two human interest stories--St. Valentine's day (tomorrow). Innocent. Fun. ABC was on the kitchen, Fox News in my office. I'm walking back and forth. Fox has a report on what people are doing on St. Valentine's day--reported on a soldier sending some home a valentine surprise and a child taking something to dad--I think it was Chic filet. ABC reported on President Obama's plans.
Another news story difference which may indicate who is beating the drum for fear and division. Fox reported on the 5th police officer killed recently (he was black, but that wasn't mentioned--there was a photo); ABC reported on a court case where a police officer had killed a black man. Race was prominent in that story. Both the number and rate of those killed in the course of committing a crime is higher for whites than blacks, but would you know that from news reporting? Why the pressure on the corporate news sources to divide the nation along racial lines?
