Media Critique: WLKY vs. WAVE and WHAS on Crime

Look at the graph below. Almost all of the points line up except for the category listed as "Crime". WLKY has almost six crime stories out of about fourteen per episode. This may just be because there is a sudden burst in crime when this data was collected but this isn't the case. Both WHAS and WAVE have significantly less stories. There are many reasons why this may be. Perhaps both WHAS and WAVE missed all of the high-profile crime stories but it is more likely that WLKY is digging up insignificant crime stories to make for a more interesting thirty minutes. This is breaking the Principle of Journalism "Make the Important Interesting". Reference the chart below for all of the data mentioned above.  

This graph shows how many stories of different types were in three different
stations. Make sure to look at the differences between the different data points
