It's pretty clear you're not arguing in good faith; but, for the sake of anyone that happens upon your post, just going to enumerate a subset of your weak assumptions. --Restrict crime stats to 75 counties (ie major cities) without also restricting fatal shootings --Assuming population ratios are constant among those counties as compared to the wider nation (required to generate percapita) --Not addressing the issue of scale between your two data sets. I don't know for certain, but I'd wager the number of violent crime incidents is at least an order of magnitude greater than the number of police fatal shootings. --Related to the population point above but not accounting for potential inequalities in the who is charged in which counties. You don't have "time" to provide a comprehensive statistical analysis because doing it right is nontrivial and very likely isn't going to conform to the views you spent so long searching the net to validate.
