[This is the transcript of my regular KVMR commentary broadcast on 7 January 2015.]

The recent police killings of two black men, and the revenge murders of two NYC police officers highlight legitimate fears that have now been brought to a fever pitch by grandstanding politicians and activist demagogues.  In New York Mayor De Blasio ran on the alleged evils and racial bias of the city’s police department.  Never mind that the data from policies like ‘broken windows’ and ‘stop & frisk’ did not support any of the popular contentions he used to stir up the city’s black population.

After the Staten Island death of Eric Garner his honor excoriated his police to the extent of inviting demonstrations in which police were physically attacked to shouts of ‘What do we want? Dead cops!’  This invitation reinforced the image of police targeting black men and ultimately resulted in the assassinations of officers Rafael Ramos and Wenjian Liu by Ismaaiyl Brinsley after posting “They Take 1 Of Ours…… Let’s Take 2 of Theirs, #ShootThePolice.”  The result is a standown of policing in the city with ongoing public shows of disrespect by the police to their mayor.  (more here)

When we step back and take a cooler and more reasoned look at the numbers that record what has actually happened in fatal encounters between police and civilians, two different pictures emerge.  Each picture is used to support arguments of why blacks fear the police, and why the police fear blacks.  And make no mistake, reasonable or unreasonable, the fear is real on both sides.


Kent Osband, who has studied the statistics of police and civilians killing each other, concludes that “while these inferences are not fair to the vast majority on either side, they are rational responses to fear and uncertainty.”  And this is especially so when each only considers their own perspective.  Using data from the FBI’s Uniform Crime Statistics database, Osband goes through a numerical analysis that would roll the eyeballs of radio listeners, so let me summarize the key findings.

Police are six times as likely to be killed by a black civilian as a black civilian is likely to be killed by police.  In contrast, police are 22 times as likely to be killed by a non-black civilian as a non-black civilian is likely to be killed by police.  This information lets blacks argue that police react far more defensively to blacks with a 1 to 6 homicide ratio than to non-blacks with a 1 to 22 homicide ratio.  That’s a pretty strong conclusion if we stop there.

However, police view the situation completely differently.  While blacks make up only 1 of 7 Americans, they account for almost half the annual police deaths.  When you consider these numbers in the analysis, it turns out that blacks are over 5.5 times as likely to kill a police officer as are non-blacks.  And police across the country know this statistic, which naturally explains why police act more defensively against unknown blacks than they do toward unknown non-blacks.

In other words when black population proportions, crime rates, and relative police and civilian body counts are included, then the reasons for the two sides fearing each other become very apparent.  “And as such, neither legislation nor indoctrination can banish” these fears.  (more here)

Ultimately, we all know that there are deeper reasons for the historical black vs police animosities that involve cultural differences, government policies, and economic factors.  But to make progress in resolving the current problems – real and perceived – Osband counsels that “each side needs to appreciate the other’s fears.  Each side needs to offer the other the respect and consideration it rightly demands for itself.”  Today self-aggrandizing politicians and activists are not helping when they stoke emotions in the service of their larger agendas.

My name is Rebane, and I also expand on this and related themes on georgerebane.com where the transcript of this commentary is posted with relevant links, and where such issues are debated extensively.  However my views are not necessarily shared by KVMR.  Thank you for listening.

[Addendum]  Upon further noodling with the data presented by Osband, it turns out that his argument from the black perspective is neither as clear nor as strong as it could be.  His concern from the police perspective is correct.  The police are interested in the likelihood (ratio of probabilities) that they will be killed when confronting a black vs being killed when confronting a non-black.  The ratio of those probabilities with the presented data turns out to be 5.46, or close enough to the stated 5.5.  In other words, a police officer knows from national statistics (and perhaps other knowledge/experience) that he is 5.5 times more likely to be killed by a confronted black than by a confronted non-black.

From the black perspective, to make the case that police are more likely to shoot a black than a non-black, the important ratio is the probability of being shot by the police given that I am black vs the same probability given that I am a non-black.  It turns out that this ratio comes to 3.13, meaning that a black person sees himself as being more than three times as likely to be shot than a non-black when in a police confrontation.  On the face of it – i.e. ignoring crime rates, fractions being in the judicial system, etc – this definitely brings up strong feelings about police being racially prejudiced.

However, as mentioned above, to bring these ratios closer to par requires much more than the current DoJ investigations and passage of new federal laws on policing.  The causes for the real fears by both sides are buried in cultural and economic issues that are not being recognized, let alone addressed, by today’s political posturings.

    Well s#!t. Here I thought that my contribution to the national hyper-ventilation du jour of cops vs blacks would be of interest, especially since I dug out the clearly indicative quantitative Bayesian behavior support for the two legitimate perspectives of fear. But nothing.
    Don’t know whether no one gives a crap anymore about that enduring problem, or I didn’t do a good job framing it, or the goddam ragheads in Paris co-opted the attention bandwidth of RR’s readership, or … . Oh well.

    I suspect it was more a case of your offering being overshadowed by current events!

    Well Doc,, the cops are giving in, in N.Y. Any petty crime they look the other way.
    Not hardly a speeding ticket, or parking violation is being issued. They have pretty much said “screw it”… The cop is the new bad guy in LIB land. They are now working with the same rules of engagement our troops had to deal with in Iraq and the other terrorist lands.
    Our cops may soon need to call an att. just to make an arrest, let alone give a bad guy lead poisoning.
    Pretty soon, they will need to call a black cop in, to shoot a black perp. How else will police keep from getting charged with racism?

    Dr. Rebane,
    I would not be so hasty to chalk it up to a loss of interest in the subject. When faced with hard numbers on a scale as you have so graciously provided above, even the most fervent “cops are racist” rhetoric heads for the safe bunker of numberless progressive thinking. The rest of us remain silently satisfied in agreement, like a man smoking a pipe after Thanksgiving Dinner, and are appreciative of your numerical and logical analysis of the subject.

    Thank you all for the kind words. Yes, I guess this piece did get some fierce competition from the recent Islamists attacks.
    On the topic at hand, when correctly posing the ‘blacks fear’ perspective in a similar fashion as the ‘police fear’ – “the important ratio is the probability of being shot by the police given that I am black vs the same probability given that I am a non-black” – I was surprised at the high value (3.13) that this ratio obtained. Comparing it to the 5.5 likelihood ratio of the police arguably legitimizes the arguments from both sides. Frankly, I was expecting that the blacks would derive less from the data to support their claims. But I stand by my assessment of what is required to effectively improve this unfortunate relationship between the blacks and the police.

    The main problem is, of course, that the topic is purest kryptonite.
    I suppose that people could draw their own conclusions via these two tables:
    http://www.fbi.gov/about-us/cjis/ucr/crime-in-the-u.s/2011/crime-in-the-u.s.-2011/tables/expanded-homicide-data-table-3
    http://quickfacts.census.gov/qfd/states/00000.html
    I strongly suspect that the FBI tables will cease to exist sometime in the near future.

    As I mentioned before, the vast majority of law enforcement (especially the cop on the beat) are good people. I see this latest “kill the pig” as an attack on cops in general. The thin blue line that separates civilized society from anarchy. If you are in the process of about to be robbed or raped and the perp is trying to beat down your door, who are you going to call? Brother Ben? A peacenik? A methhead, a gangsta crankster, your Aunt Beluea?
    Remember when Congresswoman Gabby got plunked in the head? Oh, Obama and Co. rushed to the cameras to tell us this is a direct result of vitriol speech. We need to tone down the rhetoric!!!! The Libs had a field day at the same time when they uncovered a Sarah Palin posting of Dems to be targeted for defeat at the polls with a bullseye on the picture. Haven’t see Obama/Holder rushing to the cameras telling folks to tone down the rhetoric that the President and Justice Department and mayor of New York City incited, or at least fueled the flames.
    More on the topic Dr. Rebane’s post. I asked my Dad years after he retired from the police force what was his proudest moment of being a cop. Without hesitating even a split second, he said over the course of 29 years, he never shot anybody.
    Then he continued to say that the reason there are so many police shootings is the height and weight qualifications for police officers have been relaxed too low. At 6′ 1″inch and all of 170 pounds as a rookie he almost did not get hired because he was too small. He was by far the smallest cop on the force. Every flatfoot went to the weight room after work and pumped it up. Those where the days you did not pull out a gun but wrestled the bad guys to the ground. Some cops could take a big crazied criminal and grab them by the ankles and hold them upside down.
    He continued that nowadays, some 5’4″ female cops pulls over a 6′ 8″ muscle bound black dude with an attitude and the female cop (or any small framed cop) is now more likely to pull out the equalizer. The cops feel threatened instead of showing the person pulled over respect. Yes the bad guys feel threatened and the cops feel threatened by all these street drugs that make people out of their friggin minds, some armed to the teeth.
    Michael Brown would have not been shot in the old days. The yesteryear 300 pound champion weightlifter cop would have twisted him up like a pretzel and spanked his butt or held him down on the ground until he cried “Uncle”. Yes, the cops and the bad guys no longer go thought an entire career (police and criminal career) with just a 38 and a shotgun. Both sides have much to fear.
    With all that said, the pushback will happen. The NYPD were told by their superiors not to turn their back on their cop bashing mayor anymore. Those words are falling on deaf ears. Just think of all the millions of dollars in revenue are being lost when the cops don’t write parking tickets or cite speeders. Cops are good people, but like the French and Northern Europe are finding out, you can only push good people so far until they start pushing back. Whether it is Islamic terrorists on European soil or Holder and Obama’s words against the thin blue line, people of goodwill will start pushing back. And cops are people.
