The lefty agitprop experts scan the news and determine which events have the greatest promise and then they spin the hell out of them and tell the media which to lead with. And, of course, which stories to totally smother.
Next question?
The sad thing about this is that black people cannot comprehend that the tragic death of a black teen is being exploited by the white democrat power-bosses, to herd black people into emotional reaqctions based upon the usual lies the democrat machine formulates through their guillotine deserving media whoredom.
The unaddressed tragedy is the continued exploitation of black people, whipping them into a frenzy for the political gamesmanship the democrat racists remain in power with! It is too disgusting at this stage to even be tragic.
