Nobody is lying genius. You are directly inferring that black people are more violence prone. I wonder if you would like to dig further into the metrics. Maybe try something crazy like looking at a few more social factors such as poverty level, location, age, educational resources, racism, maybe the historical reason for how urban environments came to be. If you are really feeling adventurous you might be able to tie them altogether and realize that they have only been "integrated" into our society for about 50 years. It just might be possible that the last 50 years or so haven't exactly been a downhill stroll for black people.
