On the surface, it defintely seems baffling.
However, once one understands how the MSM is really financed, who controls it & what the real purpose of the MSM is, it makes 'sense' that they would want to ignore it.
They have been lying to the public & being paid to do so for many decades. They certainly don't want to shine a light on that. Covering the 99 trial & what it exposed would also shine a light on the complicity of the MSM back when the MLK assassination happened.
Once that can of worms gets opened...... well.
