The left owns damn ever every media outlet and they have an agenda to push, so they push it. What few channels the right has will respond simply because they must counter the utter bullshit coming out of the left in order to maintain any credibility themselves. Consequently, we see "Baby Tray" day in and day out.
The thousands of young blacks being gunned down by their own all day every day doesn't fit the agenda, so it goes on as if nothing happens. The leftist agenda on race relations is, Jim Crow was just last week, whitey is to blame for everything. The question you'll never hear asked or addressed is how in the world did young black men of the 40's, 50's and 60's make better choices for themselves and their families than young black men of today will make, even though they suffered blatant discrimination, in your face racism, and very limited opportunity much more so than the black man of today has to face.
The answer is ugly, and is just too much for the left to deal with.
