If the Dept of Justice would spend less time pandering to the so called Social Justice Warriors, and stay the hell out of matters of the States, this issue would be lessened. The powers that be in many states are less and less concerned with actual justice and more concerned with pacifying the vocal minorities. The unpleasant truths that occur day in and day out are part of a reality that some refuse to accept. Those in the "dindu nuffin" portion of society are NOT the ones who need pandered to to keep law and order. The unpleasant truths seem too much for some to accept and they'd rather sacrifice justice and righteousness to avoid hurting the feelings of the vocal minority.
Absolutely. And to your point about the Feds getting involved, this has increased dramatically under Obama. Freddie Gray dies, Obama fans the flames, and out of the smoke magically appears Mosby to bring "justice." Because of Obama's grandstanding and the riots, she thinks she has the political impetus to get convictions no matter what the truth actually is, and who gets hurt along the way. This has happened more than once in the last eight years.
