Well they do, it just isn't a one for one ratio.  Additionally, it seems only black killings are being protested.  But we have come to the $64,000.00 question that needs to be answered, if possible, empirically, are the protests justified?  What number of the 200 are non-justifiable and how do they compare to non-justifiable killings with other races (Honestly, I don't like to even use the word "race".)  Then in turn, figuring out if the non-justifiable are statistically meaningful.  Of course, if it is me or a family member, "statistically meaningful" is irrelevant.
