I am not saying that there is not a problem with racism in the US police. Maybe there is. But we don't that there is until statistical evidence is produced. If there is a problem then I am as keen as the next fella for it to be sorted out.
I am actually surprised it is as low as 2.5. I thought it should be higher than that.
Is that lower or higher than the ratio of blacks to whites in prison? People in prison have been found guilty by due process of criminality worthy of imprisonment. You might expect the ratio of police fatal shootings to match this ratio.
If 2.5 is higher than the imprisonment ratio that may point to racism in police brutality.
If it is equal to the imprisonment ratio then that may point to there being no racism in police brutality.
If it is lower than the imprisonment ratio then that may point to there being positive discrimination against brutality against blacks by police.
