The nation was shocked on July 13 when George Zimmerman was declared not guilty in the controversial Trayvon Martin case. Zimmerman was charged with second degree murder after shooting 17-year-old Trayvon in what he claimed was self-defense. It's impossible to know what really happened that night, which presents plenty of reasonable doubt, hence the jury's "not guilty" verdict. Facebook and Twitter were swamped with reactions, including the heated responses from the Real Housewives of Atlanta. Here's what they had to say...

Kenya Moore: "I'm sick to my stomach. This is so sad so unfair so unjust. No one should be acquitted for killing a child after following them around … RIP Trayvon. I'm so sorry we failed you.  We send all our love and prayers to your family. We know you will watch over them in heaven #angel."

Porsha Stewart: "God Bless the Family of #TrayvonMartin 👼 Prayers are in order! Lets lift them up and ask God to keep…"

Phaedra Parks: "Injustice anywhere is a threat to justice everywhere -Martin Luther King, Jr.  #ZimmermanTrial."

Cynthia Bailey: "If you are guilty, you will never truly be free. #Godknowsall."

Kim Zolciak: "My heart goes out to Trayvon Martin's family. Thought & prayers being sent their way #NoJustice."
