nice change if when reading a story, reporting (as distinguished from opinion/editorial segments) would be consistent regardless of whether it originated from by C-SPAN, Fox or MSNBC?
You also could ask the same question about reporting a suspect's gender, sexual orientation, age, religion, political affiliation. Sometimes those could be important to the story line. Sometimes they are not. A former KKK leader in BLM is newsworthy as would be a black member of the Westboro Baptist Church.
I do believe that when the police have requested assistance finding a suspect, a complete physical description should include race. The following just wouldn't be all that helpful:
"Boston police are asking the public to be on the lookout for a suspect who attempted to rob the 1st National Bank on the corner of Mayfield and 6th Streets on Monday, January 4th, 2016 at 11:43 AM. The suspect, who fled after being asked for a photo ID, threatened the bank's senior teller, James P. Smithson, who was working at at window two with a Sportsman's Model 621 Gerber Knife that had a 5 2/3 inch double-edged blade and a Glacier Blue handle wrapped in #2 red yarn from Michael's craft store. Using a medium-tip black sharpie, the suspect wrote a 9-word hold-up note on the back of a bank deposit form, version 9.3 dated 07/2012 . Police Spokesman, Lieutenant Sarah Bell Knowlton, a 14-year BPD veteran, said the department would appreciate all tips regarding the suspect who she described as likely a human who may have been wearing clothes.
