Edit: there are two other problems:
(1) It looks like your account has been using HN primarily for ideological battle. That's not allowed, regardless of which ideology the account is battling for or against. Why? Because HN is supposed to be for curious conversation, and ideological battle is the antithesis of that. We ban accounts that are using HN primarily for this, so if you'd please stop doing that, we'd appreciate it.
(2) Given your arguments in this thread and your commenting history, I'm remembering that someone complained to us about your username being an ethnic slur (https://www.google.com/search?q=%22beaner). I emailed you about this on June 24 and you never replied. At a minimum, the username is trollish given these associations, and trollish usernames are not allowed on HN. I'm not going to ban your account for this right now because I think it's fair to give you a chance to course-correct your account to conform to the site guidelines. At the same time, I think you should be using a different username. If you want to pick a different username, we can rename it for you.
"Is it your honest interpretation of what I'm saying that [...]? Geez"
"I mean, I don't think this discussion will be fruitful now"
"This is like logic 101."
"There is an overlap in this country. There is a relationship. Do you understand that?"
"It is you making the racial connection, not me."
I'm not sure if the data exists for this. You'd need to record a huge sampling of police interactions and somehow classify the behavior of the civilian independent of the police to see if they were "aggressive" or "escalated", which is quite difficult. And part of the issue is that many behaviors that police often claim are aggressive are obviously not, so who gets to define these words? Very tough.
Overall, I think I agree that given the data we've discussed in this thread, there's no way to prove whether or not disproportionate deaths are caused by police bias. I started this conversation to respond to a question in the Twitter thread you linked: "I'm going to keep tweeting this until someone can explain to me how this is possible if there is truly pervasive racial bias in policing". I maintain that it is absolutely possible, and seems likely given the data we have here, but definitely not proven.
"I looked at it and the study doesn't account for anything. For example, if a certain demographic were 2x more likely to die in an encounter, but 4x more likely to respond to a benign pullover with violence, then they're actually 2x more likely to be treated with less force than their actions require.
This is basic, the study (at least on my glance) appears to not account for anything like this at all."
