Obviously historical racism is the huge cause here. But you cannot just write off the crime rates due to different policing.
Poor Black neighborhoods are simultaneously over and under policed. Gangs and criminals have free reign and then cops capriously make a show of force.
They are under policed ("guardian" model) and overmuch hostilely occupied by the police ("warrior" model).
They are the places most in need of effective community-oriented policing, and the places that get that kind of policing the least.
To my knowledge, not one of them were ever investigated, searched, arrested, prosecuted, or convicted of a crime. (Well, there was that one guy who had a close call at a border crossing on a trip to Amsterdam.) I can't think of any way in which their behavior would be reflected in formal criminal statistics. But let's not pretend that "crime" of this sort is not rampant among white students on college campuses around the country.
A large fraction of the point here is that criminal statistics reflect who our society chooses to enforce its laws upon.
Crime is a complex system that involves more than just the two axes race and violence.
For those that actually believe the GP might have some ground to stand on, the least they could do is to link to some sources or resources.
I almost always provide links to sources that provide a reasonably analytic angle.
They are generally ignored or misunderstood. Because, you know, (structural) racism.
Lastly, above and beyond any correlation between testosterone and crime, how do you propose to use this information to inform policy decisions? My main gripe in this fantasyland of HBD-speak is that people use this information as "scientific" grounds for enforcing their racist policy predispositions. I'd like to hear where you think you would take this testosterone point, but all too often people (and unfortunately, I get the impression that you are one of them) imply that these few studies are grounds for damning and castigating entire populations because of their perceived inferiority and incorrigibility.

EDIT for posterity: I would like to point out that you posted your cousin/uncle link upthread after I posted my GP comment above. I wouldn't have made as strong a comment had I seen links or sources.
Your previous reply sounded a lot like those "you are not allowed to say this" stuff that does a lot of harm, because it suffocates discourse.
So thanks for posting a factual follow-up, we need more of those and less of the political correct group-think dismissals.
Ex: "Melanin is positively correlated with crime. <Insert some unsubstantiated purely conjectural causal explanation about how melanin effects the psyche>" is exactly the same argument, and is (I hope obviously) damn racist.
The study cited also doesn't say what you think it does, and your misreading is obnoxiously wilful, to the point that it's clear you're looking for evidence to back something you believe a priori. But someone else has already taken that on.
Anyway, the bar for these sorts of claims is high for a reason: people have made these "black men just have medical differences that make them more susceptible to violence/rape/murder/crime" arguments since the existence of modern medicine. The evidence behind these claims has always been pure bullshit racism masquerading as science.
(Structural) sexism? Poverty? Poor fashion sensibilities?
> (Structural) sexism?
In the specific form of paternalism this would certainly seem to be a factor, at least.
Second, there are tons of alternative explanations (e.g. socialization). Nature vs. nurture is adolescent-level stuff, and obviously males and females are socialized differently. Stop being thick.
Third, that's not how science (or anything except religion) works. You don't get to make fallaciously substantiated conjectures and then demand everyone believe them until the core claim is disproven.
edit: Oh wow, based on prior coments you're actually just straight up early 20th century style racist, or a troll, or both. Done engaging you, and really hoping you're just a stupid troll and don't believe anything you're saying here.
Some of that is racism in crime reporting and law enforcement behind the stats, and some if it is a real disparity, and at least some of that real disparity -- perhaps all of it -- results from the fact that black people in the US come from a cultural which has very different attitudes due to a very different experience with authority historically, with de jure discrimination and overt police repression of the black community extending into living memory (and even stronger farther back where it still exerts considerable cultural influence), which has a considerable impact on attitudes towards institutions of authority and the broader society.
Piling more racism by the broader society on top of that is not going to alleviate that problem.
