No description of the New Orleans shooters?

Police were accompanying the parade and saw the three offenders run off and yet the reports give no whiff of a description of the perps.   I have read through every report of the shooting that Google news threw up.

I surmised that the reason for the silence might be that any reasonable attempt at description would include the word "black".   And I was right.  CBS, of all people, have breached the wall of silence.  They couldn't bear to mention the B-word but they went close. We read from them:  "Police are looking for three suspects, one of which was described the suspect as a dark skin male, 18-22 years old with short hair, a white shirt and blue jeans."  Poor grammar but real information. 

I am guessing that reporting of this crime will rapidly fade away.
