Honduras may be making progress against violent crime. "Three years ago, Honduras had the highest homicide rate in the world. The city of San Pedro Sula had the highest homicide rate in the country. And the Rivera Hernández neighborhood, where 194 people were killed or hacked to death in 2013, had the highest homicide rate in the city. Tens of thousands of young Hondurans traveled to the United States to plead for asylum from the drug gangs’ violence.
South Africa is 80% black with black leadership. 80% of the police are black. This does not eliminate police violence. Almost all the violence is intra-racial. Obviously, racial differences are not the cause. "For citizens and police officers alike, South Africa is a more dangerous place than the United States. Its population is much smaller, but by most estimates, South African officers are killed at higher rates than their American counterparts. Likewise, South Africans are killed by the police at higher rates." Class differences, police culture, and political culture may be playing roles
