I'm not sure I follow. What you mean by "the pattern (of violence such as murder and rape) stays the same"? The pattern of violence that black people do?
If so, that's absolutely wrong that it stays the same "no matter where you look on this planet, no matter what the history of that location is, no matter how far back in history you go".
In fact the amount of violence perpetuated by "white people", from the Crusades to the Holocaust, colonial wars, Cold War proxy wars, etc, and onwards, is so much higher, it's not even funny. And not even at their own house -- they pissed all over the world.
