The one depicted is in the St. Louis police force with eight years experience.
The Darren Wilson in question was employed by the Ferguson police force for the past six years.
I’ve noted that discrepancy and I’m betting that you are right.
I did find that there are only 3 blacks out of the 53 officers on the Ferguson Police Department. If so, the likelihood that the Ferguson Darren Wilson is black is about one chance in sixteen.
OTOH, maybe this guy transferred from the St. Louis PD to the Ferguson PD six years ago. Possible.
In any case you can bet there is a real race on to find a photo of the real guy. The WP, the NYT, the LAT and the rest need to put this “Black Darren Wilson” story in the trash heap mucho pronto.
