Don't they teach journalistic integrity or ethics and standards in journalism schools anymore?

The answer is obvious. But you have to remember, much of what people think of as "news" is really more like "infotainment". Do you consider anyone on "The Today Show", "Fox and Friends" or "Good Morning America" a journalist, or what they do as reporting the news? So of course they can interject whatever they want. As for someone like Katie Courek, what she does definitely crosses the line, as do many opinion or ysis pieces in papers like the New York Times and Washington Post that are printed as if they are new articles.
