You are worse at grammar than I am. The sentence you corrected did not need a comma. It also could have been done with a few other punctuation marks as well. You are missing the point of why I  corrected you. You tried to manipulate the numbers and it failed.

What exactly am I manipulating?  That most black homicide homicide victims are killed by blacks, not white people wearing silicone masks and gloves?  
Hey I'll step out on a limb and manipulate some more statistics.  My point was that Democratic politicians were in large part responsible for the comparatively high homicide rate among blacks in Chicago.  Here's a list of the cities in the USA with the highest homicide rates and the party affiliation of their mayors.  
1. East St. Louis, Illinois, 101 murders/100,000 people - Democrat
2.  Chester, Pennsylvania - 67/100,000 - Democrat
3.  Gary, Indiana - 60/100,000 - Democrat
4.  St. Louis, Missouri - 60/100,000 - Democrat
5.  Baltimore, Maryland - 51/100,000 - Democrat
6.  Flint, Michigan - 46/100,000 - Democrat
7.  Detroit, Michigan - 45/100,000 - Democrat
8.  New Orleans, Louisiana - 44/100,000 - Democrat
9.  Salisbury, North Carolina - 41/100,000 - Democrat
10.  Danville, Virginia - 38/100,000 - Democrat
United States of America as a whole - 4.5 murders/100,000 people
In a couple of instances I didn't verify the city has primaries, but did determine the current mayor identifies as a Democrat.
