The media commonly uses perception rather than facts in order to create public opinion. Perception is formed by what the media presents in images much quicker and more efficiently than what it presents in words.

Why picture a White woman in an article about a crime committed by a non-White? Because they know it leaves the impression that Whites are also criminals, and they cannot be accused of "racism" reporting crimes committed by aliens.
For this same reason, when on infrequent occasion a news report containing black-on-white crime is reported, television news producers usually have a black or other non-white reporter present the story.
