I can appreciate your willingness to ask hard questions and would like to respond to your last set about the comparison of whites vs POC police shootings. I am a statistics guy and went to a database supplied to us from the Washington Post and found some numbers interesting.
So let's first break down the population of the united states:
1. Whites make up 72% of the population
2. African Americans make up 12.6% of the population
3. Hispanics or Latinos make up about 16.3% of the population

Now lets break down police shootings, so far for the year 2018:
679 people have been shot and killed by the police. Of those we have race data for 498 of the victims. From the demographics we know:
52% (261) were white, meaning that 72% of the population makes up for 52% of the fatal shootings
24% (121) were african american, meaning that 12% of the population makes up for 24% of the fatal shootings
19% (94) were hispanic or latino, meaning that 16% of the population makes up for 19% of shootings.
When we break it down to unarmed people
34 cases where the victims were confirmed as unarmed (7%)
Of the unarmed cases 17 were white (50%), 72% of the population accounts for 50% of unarmed fatalities
13 were african american (34%), 12% of the population accounts for 34% of unarmed fatalities
4 were hispanic (11.7%), 16% of population accounts for 11.7% of unarmed fatalities
Of those shot that were fleeing the scene there were 14 people unarmed and fleeing the scene (which is an important statistic):
7 were white (50%)
6 were african american (43%)
1 was hispanic (7%)
Now if we were to control for those that fled the scene here is what we come up with.
20 cases where people were unarmed and not fleeing the scene (which would be were biases would manifest themselves IMHO):
10 were white (50%)
7 were african americans (35%)
3 were hispanics (15%)
Even in these 20 cases, there is not a report on this database about how many were exhibiting violent behavior, which would be an important measure.
If we were to use percentages, it would be highly misleading as there are only 20 cases were biases could manifest themselves based on race. That is 20 out of 498 race reported (4%) of fatalities. I think that 20 is a very generous number considering the fact that the measure of violent activity against the police is not a measure in the database.
It is my opinion that if 4% of all fatal police shootings could be subject to bias, that the police are overall doing a good job, and that before we jump to conclusions based off percentages, we need to look at sample sizes.
That being said, I always feel it in my heart when someone does go down, and mistakes are certainly made. I won't even deny that some of the numbers from this database could indicate bias (more nuanced discussion needed), and certainly would understand if it was my son or daughter who fell victim and have a need to protest. I respect that right to protest, even if it is annoying for me, or something that I disagree with.
