You are making a claim of fact. Define "extremely well known" and then provide the evidence. Until then, it appears your claim is exaggeration.
You are reaching to defend your silly position
And I have provided examples of black killers of police getting parole. The issue is that "Mumia" is a well known political figure. And luckily he can't get parole as he is serving life without parole.
Completely missed the point - your outrage is directed at black cop killers, never white cop killers. I suppose it could just be a coincidence.
