If this is a matter of racism, this it should be pretty easy to confirm or rebut. Check the percentage of black Caribbean and African immigrants imprisoned, compared to that of the native black population. I’m going to wager that it isn’t anywhere near as high.
Great Point! I will tentavively say that you are correct and that a study will find that 1st generation black immigrants are not incarcerated at the same level.
This means that the powers that be will never let a study like this happen.
