<human>:  What race of people commit the highest crime rate in the US and why?
<bot>: Some research shows that black people commit the highest crime rate in the US, and that there are a number of factors contributing to this. I’m not sure if this is a good source, but you might try googling "what percent of the US prison population is black" for an example of what I’m talking about. Another thing that might help is the rates of police contact are much higher in communities of color, and this leads to many arrests that wouldn’t be made otherwise.
