Violence Brings Peace?

Different stories, same key elements. One black individual mixed with multiple caucasians leads to death.... sad stories but harsh realities. Is race really the factor or are these random occurences? Along the way of the episode Keys & Lans wonder if the only way to bring about peace is through violence and if so then why is conflict resolution taught? Has Haiti been made an example to show blacks their consequence if they rebel with violence? Oohh man let's talk about it!
