I'm gonna be brutally honest and this isn't to say it's right, but after that video surfaced of him pushing that store owner, most folks tuned Ferguson and Mike Brown out. Again, it's not right. But that video contradicted what his friend said in many folks' eyes, which soured the whole situation. Many are clueless to the new developments as a result. That's just the world we live in. Once folks in large numbers tune it out, the media did the same.
Also, the average person has their own hurdles to jump over so they aren't gonna spend too much time on that of others. That sounds selfish in a way I guess but once again it's brutal honesty.
No worries though, when the verdicts roll around it will get a new bout of attention.
