Cops in Conservative Cities Shoot & Kill More Often

Forbes came out with a list of the 10 most conservative and liberal cities in America.

Top ten conservative, in rank order:
Mesa
Oklahoma City
Virginia beach
colorado springs
Jacksonville
Arlington, TX
Anaheim
Omaha
Tulsa
Aurora
Top ten liberal, in rank order:
San Fran
DC
Seattle
Oakland
Boston
Minneapolis
Detroit
NYC
Buffalo
Baltimore
I'm not going to argue with the rankings. I don't really care. But here's what I thought: I bet police shoot a lot more people in the conservative cities. Related to and perhaps correlated with the fact police shoot more people, per capita, in states that are more white.

How's this for a working hypothesis? Other things being constant (they rarely are), police shoot more people when nobody cares about police-involved shootings. And white people -- particularly conservative white people -- don't really care about police-involved shootings. Period. No matter the race of those shot. And when there's never any pushback or criticism of police, laws and training and culture do not change.

Based on Washington Post data from January 2014 through September 2016, the annual rate (per 100,000) of police-involved homicides in the top 10 conservatives cities (n = 82) is 0.61. The annual rate of police-involved homicide in the top 10 liberal cities (n=78) is 0.20.

Now New York City accounts for a lot of that, in terms of population. But even were one to remove NYC for simply being too big, the rate in the liberal cities is 0.39, or 64 percent of the conservative city average. Even without New York, cops in the most liberal cities are more than a third less likely to shoot and kill people. Are other factors involved? Sure. And they might be correlated to political ideology. Go figure them out, if you wish.

Also of note, and I'm just looking at 2016 murder numbers, the murder rate in the top ten liberal cities in 9.96, which isn't that much higher than the homicide rate of 8.01 in the top 10 conservative cities. If you take NYC out of the equation, the homicide rate for the other 9 liberal cities goes way up to 20. But if you consider that murder is higher in the top-10 liberal cities, the lower rate of police-involved homicides is all the more impressive.

I mean, think of it this way: community violence and police-involved violence are very related. A lot of the people police shoot are violent criminals with guns, some in the process of using them. The more violent criminals there are running around shooting people, the more people police will shoot. Always has been, always will.

That said....

There were 138 murders in DC last year and every year (for the past 2.75 years) police shoot and kill 4 people. In Tulsa and Oklahoma City (which combined have 1 million people) there were 142 murdered last year and police shoot and kill 10 people. That's a big difference. Police do shoot a lot more people out west. And it's not just in conservative cities. In fact, given the low levels of murder in Seattle and San Francisco, the high number of people killed by police stand out.

Anaheim had but 7 murders last year and police shot and killed 5 people since 2015. In Boston, Arlington and Detroit, police also shot and killed 5 people in the past 2.75 years, but there were 49, 21, and 303 murders, respectively, in these cities. Why? My guess: a combination of cops being better trained, less afraid, and less trigger happy in these cities combined with cops also being less proactive.


Here's the raw data I used. (Rate modifier is used in column G, (population/100,000)/2.75, because I'm using 2.75 years of police-involved homicide data.)

Quality Policing Podcast

Nick Selby and I have a new episode over at qualitypolicing.com. Among other things, we manage to have a rational debate about gun control. Imagine that.

It's Episode Five. (And yet somehow, from two people who claim to be good with numbers, we now have ten episodes.)

Two-year homicide increase in cities

Now that the UCR data for last year is out, here is the homicide rate increase in cities over 400,000 people. This is two year, 2014-2016.

Homicide is up in 40 of the 48 largest cities.
