crime rates

How many crimes does your police department solve?

Fewer than you think, unfortunately.


Violent crime in America has been falling for two decades. That’s the good news. The bad news is, when crimes occur, they mostly go unpunished.

In fact, for most major crimes, police don’t even make an arrest or identify a suspect. That’s what police call “clearing” a crime; the “clearance rate” is the percentage of offenses cleared.

In 2013, the national clearance rate for homicide was 64 percent, and it’s far lower for other violent offenses and property crimes.

University of Maryland criminologist Charles Wellford says police have shifted priorities over the decades.

“In the ’60s and ’70s, no one thought that the police should be held responsible for how much crime there was,” Wellford says. Back then, he adds, police focused on calls for service and solving crimes.

In more recent years, he says, police have been pushed to focus more on prevention, which has taken precedence over solving crimes — especially non-violent offenses.

In short, the falling crime rate we’ve enjoyed may come at a cost: police indifference when you report your stereo was stolen.

I admit, that wouldn’t have occurred to me. I would have thought that with less crime, police departments would be more able to solve the crimes that were committed, since there would be less of a workload. I’m not a criminologist and I haven’t read any research on this, but my initial reaction here is to be a little skeptical. In what ways are police departments focused on crime prevention, and what evidence is there that those methods are working? My gut says that police departments these days – really, for the past thirty or so years – have concentrated on drug-related crimes. While I would agree that there’s some ancillary prevention benefit in that, we all know that this comes with a variety of costs. Maybe the national effort to decriminalize some drug offenses will have the benefit of allowing police departments to once again focus on solving the crimes that really do victimize the public.

The article comes with a utility to look up the crime clearance rates in your own community. Here’s what it showed for some of Texas’ biggest cities:

All violent crime Homicide Property crime City 2011 2012 2013 2011 2012 2013 2011 2012 2013 ====================================================================== Houston 46% 39% 37% 90% 70% 76% 13% 12% 11% Abilene 47% 49% 64% 80% 100% 100% 25% 22% 20% Amarillo 40% 45% 48% 60% 100% 44% 18% 19% 22% Austin 49% 49% 57% 93% 87% 100% 12% 12% 13% Beaumont 70% 70% 69% 100% 100% 75% 23% 28% 27% Corpus Christi 54% 53% 45% 67% 63% 100% 20% 23% 19% Dallas 38% 40% 37% 65% 58% 60% 13% 11% 11% El Paso 48% 47% 49% 88% 96% 80% 18% 20% 22% Fort Worth 36% 38% 39% 61% 80% 86% 14% 16% 17% Laredo 80% 80% 79% 64% 88% 100% 20% 24% 28% Lubbock 30% 32% 34% 50% 73% 100% 15% 15% 19% McAllen 56% 66% 38% 50% 100% 0% 20% 22% 16% Midland 66% 68% 59% 100% 75% 40% 22% 25% 27% Plano 54% 51% 47% 80% 100% 100% 22% 22% 19% San Antonio 48% 36% 37% 80% 70% 75% 12% 11% 12% Waco 56% 56% 55% 91% 67% 50% 23% 23% 26%

Note that these are all for the above-named cities’ municipal police departments. I limited myself to cities that I could think of that had a population of at least 100,000. (Galveston, in case you were wondering, has about 48,000 people.) “Violent crime” includes “Murder and non-negligent manslaughter”, which I characterize above as “Homicide”, “Robbery”, and “Aggravated assault”. “Property Crime” includes “Burglary”, “Larceny-theft”, “Motor vehicle theft”, and “Arson”.

Don’t be too mesmerized by the Homicide solve rates for smaller cities. The total annual number for these crimes in cities of, say, 100,000 to 200,000, is often in the single digits. McAllen, for example, had 4 homicides in 2011, one in 2012, and two in 2013. In a few cases, such as Beaumont for 2011 and 2012, the number of murders solved was greater than the number of murders. My guess is that the solved crimes included cold cases, but there was no explanation on the site. I just listed those as 100% to avoid weirdness.

What stands out to me in all this is that generally speaking the smaller cities had much better solve rates for property crimes than the big cities. In Houston, Dallas, San Antonio, and Austin, the solve rates for property crimes never topped 13%, but in the smaller cities it ranged from 18% to 28%. Fort Worth and Lubbock were the outliers there, on the low end. I’m not sure what to make of that, but it sure is interesting.

What application does this have to the 2015 Mayor’s race? (You knew I was going to get around to that, I’m sure.) Well, in addition to my wish that the candidates will eventually start to talk about public safety in a more comprehensive way, I’d think that a candidate who promised to have his police force concentrate on solving property crimes might be able to sway a voter or two. Lord knows, the Nextdoor discussion list for the greater Heights area spends a lot of time on break-ins and thefts and the like. Given how many of these crimes do go unsolved today, it seems to me there’s some traction to be gained on this issue. Just a thought.
