You really don’t understand the concept of percentage of population, do you? Let me try an extreme example to see if I can get you to understand a very basic statistical concept.
Pretend there is a population of 15 people and a population of 10,000 people. Now pretend that cops killed 10 of the 15 people in the last year and 20 of the 10,000 people.
Technically, cops killed more of the larger population than the smaller, but in terms of percentage of the population, cops killed 66% of the small population and 0.2% of the large population. Anyone with even the slightest understanding of statistics would understand that cops are killing the small population well in excess of the large one.
