Well at least you aren't disagreeing with the math. But apparently it doesn't matter to you that the sample size went from 1200 to a few dozen.

Why does it matter what I am, I have a degree in economics and I am familiar with economics and statistics even though I am not an economist or statistician. Just as I don't have to be a mathemetician to know that pi is the ratio between a circle's circumference and its diameter; I don't need to be a statistician to know that 37 deaths over 3 years is not enough to declare a racist epidemic as severe as you describe. Pro Publica is feeding you factoids to rile you up.

The only actual peer reviewed study published by a Harvard economist in a prominent journal says that cops don't really shoot blacks significantly more than whites. The differences to the extent they exist can be chalked up to statistical noise.

The one statistician that supported the pro publica statement has withdrawn his support. It is effectively P Hacking the data.

Police shoot and kill ~1000 people each year. You are saying that based on ~12 shooting in each of 3 years you can conclude something?

I'm not saying that the peer reviewed study is irrefutable but pro publica is a news organization. They are good at uncovering and reporting news. It is indeed an interesting factoid that in the population of 60+ kids 15-19 shot by police from 2015-2017, 37 of them were black. But this is a factoid because it is a cherry picked fact that distorts the truth. This factoid is not enough to reach the conclusion that cops shoot black kids at 21 times the rate that they shoot white kids.

Why is it that you think that a news article is the equivalent of a peer reviewed study?
