So 30% of the population is doing over 50% of the murdering... sucks when reality strikes eh..

It is not 30%, it is 14%.

According to the United States Census of 2010, there are 45,284,752 African Americans residing there, costituting for 14.6% of the population. So, 14.6% of the population is committing 47% of the murders. The non-Hispanic whites (63.7% of the population) commits less than 20% of the murders (the 48% given in the table is false, as more than half of the amount is done by Hispanics).
