What Do the Killings in Charleston, SC mean for Black People?

The Charleston, SC shooting happened about 10 days ago and I'm still processing the pain and weight of this mass killing in light of the recent activism against systemic racism in America.  We're definitely in a moment right now with Black Lives Matter, protests and social media documenting every second of it all.  I noticed that right after the shooting and the killer's capture the focus became the immediate forgiveness by the victims for the killer and the confederate flag's influence on the mind of this maniac. 

As an adult, I know very well that forgiveness is work and it clears our spirit and minds to move on.  Holding onto hate and anger, no matter how justified, just hurts you.  But timing is everything and you can't just rush to forgive when you haven't processed the emotional state you're in whether its anger, pain, confusion, etc.   I don't want to judge these survivors rush to forgive if it helps them deal with the enormity and pain they're dealing with, but it is OK for black people to be more than angry when loved ones are sensely taken by racial violence.  And yes, I know that sometimes forgiveness needs to happen even when there's no justice, because again, forgiveness is for your mental and spiritual health.   But it's more than appropriate to have a healthy rage or anger when something like this happens, it's just not healthy to stay there.  We are human beings and need to allow ourselves to feel the full range of human emotions without judgement or need to make society feel safe from our anger. 
 
Then I got to pondering this whole confederate flag situation in South Carolina and what does it really mean to the lives of black and white people in the South.  Black people have been living with confederate flags atop their municipal buildings and universities for over 150 years.  For whites, it has been the symbol of white southern pride and rebellion.  For blacks, it has represented southern white ignorance, terror and violence.  So yes, this flag's run in public spaces needs to come to an abrupt end.  It's just time.  But how is this really going to impact the daily lives of black people in South Carolina?  They're still going to experience racism and resistance to experiencing the fullness of life that America offers so many others.  It seems to me like they could've leveraged this tragedy to improve their political power and not give the momentum of this moment to banish a symbolic relic of the South's former glory.  Laws were changed because 4 Little Girls were bombed in a church basement on Sunday morning.  They took an unspeakable tragedy, and used political strategy to move us forward with concrete civil rights legislation.  We had something tangible to show our future generations that children literally gave their lives to change the laws of this land.  They did not die in vain.  So this mass shooting, act of terrorism, will have what effect?  What will it change, really?  We need to be more concerned with what POWER (politcal and economic) is to be gained and not the demise of symbols of white supremacy.  The South is still chipping away at our voting rights and our leaders are giving energy to the confederate flag.  Somebody help me.
