Looking at all the turmoil on the continent of Africa, could it be said that blacks are more violence pron?

Does tribal violence (still today in Africa) equal gang violence in American cities today. Blacks killing blacks for their gang/tribal affiliations?.... No, I don't want to come off as raciest it is just a question. Or is this an educational problem. The greater your education level the less likely you are to use violence as a means to settle a difference,.
