The narrative that blacks are violently targeted by police officers out of racism is so entrenched in the media that journalists sometimes forget that some police officers involved in widely-reported violence with black suspects are either black or Hispanic, and not white.

On Thursday's Erin Burnett OutFront, CNN correspondent Drew Griffin mistakenly identified the police officer who tragically killed black motorist Philando Castile as being "white" even though former Officer Jeronimo Yanez is Hispanic.

The CNN correspondent's mistake came within a piece recounting reports that Russians have tried to use social media to heat up political tensions in the United States. After recalling the case of an apparently Russia-based group called Don't Shoot Us that paints American police officers as biased against blacks and tries to inspire protests, Griffin recalled:

The Russians not only exploited divisive racial issues in the U.S, CNN has learned Don't Shoot Us was operating almost a rapid response to those shootings. In Minnesota last July, the day after Philando Castile was killed by a white police officer, Don't Shoot Us was using social media to organize its own protest.

He added: "The effort failed because local community members determined something was wrong. Turns out they were right, and their suspicions had Russian links."

NBC's Pete Williams notably made the same mistake last month.

Of course, prominent left-leaning American news sources like CNN and the broadcast networks also do their part to stoke racial tensions as they selectively spend much more time reporting on blacks who are killed by police officers -- even though whites killed by police outnumber blacks by a 2-1 margin -- giving the impression that it is nearly always blacks who are targeted.

Former Officer Yanez -- who was acquitted of criminal charges -- notably resigned his position after making a severance agreement with his police department. And Castile's mother received a $3 million settlement from the city.
