There will be no coverup.....just my opinion but this crime supercedes the race issue.
The city of Atlanta is all about pecking-order patronage. That's from top to bottom. Nothing's going to change there. Wait and see. Oh, there will be some new window-dressing and maybe even a commissioned "study." But don't think for one minute that the concept of personal responsibility and personal merit is going to be reinstated.
It's not the race issue, it's the sex issue - whether women should be allowed to be EMTs or jailers. Go back up the thread and you'll see people complaining about watching a woman EMT unable to load a stretcher-borne patient into an ambulance alone, and of course the whole thing started with the big bad criminal disarming the allegedly woman jailer.
Gotta a lot of complaints, too, about defendants not being routinely trussed up and rolled into court on dollys...
