I’ve noted previously that murder is on the decline in 2009 for the District of Columbia, and today’s Post brings the news that the tend seems to be going national:

Violent crime has plummeted in the Washington area and in major cities across the country, a trend criminologists describe as baffling and unexpected. The District, New York and Los Angeles are on track for fewer killings this year than in any other year in at least four decades. Boston, San Francisco, Minneapolis and other cities are also seeing notable reductions in homicides.
In his excellent forthcoming book on crime Mark Kleiman makes the point that it’s much easier for a law enforcement system to be effective when there’s relatively little crime. With few people committing offenses, it’s pretty easy to monitor crime hotspots and to deploy swift and effective punishment. And because it’s pretty easy to capture offenders and punishment for offenses is likely to be swift and effective, people tend to be deterred from committing crimes. Which makes enforcement easier which makes crime decline which makes enforcement easier and on and on and on.
In other words, there’s at least some reason to expect that the past 15 years’ worth of success at better controlling crime in many of America’s major cities will just have a lot of momentum that can carry us forward even through unfavorable labor market conditions.

As private protection expands and reduces crime, government and police although not really doing anything differently will ultimately take credit.
This has been the case for the last 30 years.

July 20th, 2009 at 3:28 pm
Not too surprising, when you look at the numbers. Once cities started to empty out in the late 50s and early 60s, the violent crime rate started to jump. During the 90s the reverse happened and in many cities the exodus terminated or reversed, and LO AND BEHOLD the violent crime rate dropped. Washington DC is looking at the first population increase since the 1950 census.
So which came first, the drop in crime or the increase in population? And which came first, the spike in crime or the decrease in population?
July 20th, 2009 at 3:40 pm
Big jump in arson. Hmmmm. One way to cope with a failing business is to burn it down and collect the insurance. It seems people might be taking that option. Unfortunately for them, the police and insurance companies have become quite good at such investigations. But if your business failed and you are losing your house, maybe being in jail for arson isn’t so bad. Free room and board at least.
July 20th, 2009 at 3:41 pm
Washington DC is looking at the first population increase since the 1950 census.
Isn’t this evidence that the crime rate reduction isn’t just about population changes? After all, this isn’t the first year crime has gone down in DC since 1950.
July 20th, 2009 at 3:58 pm
What I find odd about this chart (not the murder, that’s great news) is that robbery is up, but burglary is down, and theft is up while auto theft is down. Now I would expect in a bad recession for all forms of property crime to go up, but that doesn’t seem to be the case.
Obviously, this is hard to parse unless one can tell the difference between these crimes (I’m guessing that robbery is sticking someone up, but burglary is busting into a house, but then what’s theft? Auto theft is fairly obvious).
So what’s going on?

July 20th, 2009 at 4:05 pm
“So what’s going on?”
Auto theft going down is pretty obvious. Many auto thefts are done by professionals who strip the cars and sell the parts. With car sales down, the market for stolen auto parts is down as well. Burglary is harder to explain. Maybe it’s just that with more people unemployed, people are home more often. So there are fewer opportunities.

My home town saw the largest drop in crime of any city in America during the 1990s. There is virtually no “private protection” in this city – Lowell’s a real city, you see, not some soulless collection of gated subdivisions. There was, however, a radical concept called “community policing” invented here.
Oh, and a whole lot of money spent on lead paint reduction, fwiw.
July 20th, 2009 at 4:40 pm
I don’t know the answer to this, but as more rich folks move into the big city, and poorer parts become more hipsterish, maybe the crime’s just moving to inner ring suburbs?
July 20th, 2009 at 4:44 pm
I wonder if there’s any difference in the racial breakdown. Maybe Obama’s election convinced a lot of formerly disaffected black people that the country is on their side, thus reducing black crime disproportionately?
A lot of it could also just be that the 2007 oil spike and the shift in focus of a lot of government-assisted housing programs toward poverty dispersion is causing urban gentrification.
July 20th, 2009 at 4:45 pm
I don’t know the answer to this, but as more rich folks move into the big city, and poorer parts become more hipsterish, maybe the crime’s just moving to inner ring suburbs?
FBI stats suggest that the reduction in crime is nation wide and not confined to large cities.
July 20th, 2009 at 4:53 pm
It’s probably down because of all the “criminals” this country has deported.
July 20th, 2009 at 4:54 pm
Does the data really oppose the theory that crime depends on the state of the economy? Property crime is more or less flat, while violent crime is significantly down. That’s consistent with a universal anti-crime trend (improved policing, changes in demographics, glowing waves of Obama-induced benevolence) combined with a economy-related pro-economic-crime trend.

All else being equal, shouldn’t a decrease in auto sales cause an increase in auto thefts? After all, a 1993 Ford Explorer is going to need more replacement parts than a brand new 2009 Ford Explorer.
Also, with a bad economy, shouldn’t there be more people looking to save money by buying black market parts for their car?
Kyle
July 20th, 2009 at 7:06 pm
So you guys straight face believe that mandatory minimum sentences and throwing money at police budgets provided the large majority of improvements in crime in the last 30 years? In the face of the private market going from perhaps 10 billion to more than 300. Those people investing in private security were just completely irrational and their investments were all for naught?
There sheer idiocy required to develop the ideologies on display by you two stooges makes me truly wonder about the future of this country.
July 20th, 2009 at 7:42 pm
“After all, a 1993 Ford Explorer is going to need more replacement parts than a brand new 2009 Ford Explorer.”
True, but there are many 1993 Explorers in the junk yards. If you need a part, that’s where you’d go. The real money in stolen auto parts is in the newer parts. When you crash your new Lexus, you’ll need a new door now and can’t wait for one to show up at the junk yard. So someone steals a new Lexus and you and several other people get all the needed parts.
“shouldn’t there be more people looking to save money by buying black market parts for their car?”
Most people don’t know they’re getting stolen parts. You don’t get them at Napa or Pep Boys. You get them when you take your car into the shop and the shop buys them for your repairs. And they buy them from a fairly reputable parts dealer, who got them from a less reputable dealer, who bought them from a chop shop. But that really only applies to new parts. Parts for old cars are readily available from junk yards. It’s really the number of new cars still under warranty that determines the stolen parts market.
July 20th, 2009 at 8:02 pm
Never having owned a car, I hadn’t thought of the junk yards as a source for spare parts. Makes sense.
I thought that new cars getting repairs under warranty are getting new parts straight from the manufacturer, without the middlemen through which stolen parts can sneak in. For non-warranty repair work (i.e. the new door for the Lexus you just crashed), I now see how stolen parts find their way into the car.

July 20th, 2009 at 8:26 pm
I’m inclined to doubt the significance of the arson jump, fostert. 24 and 28 are both quite small numbers. If arson follows a Poisson distribution with a mean annual incidence of 25, then 24 and 28 are within one standard deviation (5) of each other.
July 20th, 2009 at 9:38 pm
“I thought that new cars getting repairs under warranty are getting new parts straight from the manufacturer, without the middlemen through which stolen parts can sneak in.”
Not really. Now, if you have a Mercedes, you’ll go through an authorized Mercedes repair shop. And they will almost always have parts straight from the factory. On a Lexus, not so much. You’ll probably go to a private shop for the work. They’ll take a warranty job because they know they’ll get paid by the manufacturer. That shop will look for parts online to get the best price. If you have an American car, anyone can do the work and will accept a warranty job. And the American companies will work with anyone who meets basic certification requirements. Lexus doesn’t control things like Mercedes does. They don’t need to buy fresh parts because they aren’t under a certification contract that requires them to buy new parts.
I’m familiar with this because I own a 1976 Mercedes 230. Ain’t many of those in junkyards, and there are even fewer of them to steal. I have to get factory parts for the less car-specific things. And if I need a quarter panel, I pretty much have to wait for someone to crash one without damaging the quarter panel I need. Fortunately, the 1976 model was a Frankenstein contraption that used 220 body parts, which are much easier to get than the 1977 230 body parts. But if I need a new crankshaft, I have to have it custom manufactured. I’ve been through that nightmare, and it was $8,000, which somebody else had to pay because they fucked up an oil change. And if I need a new exhaust air return rail, well, that’s not going to be easy. It will have to be custom made, but hardly anyone does that kind of work these days. It would be cheaper for me to learn inert gas welding, buy the equipment, and do it myself.

Anybody who cares to consider the issue of crime reduction over the past few decades, since Lowell experienced the largest reduction in crime of any city in America during the 1990s.

I will give you $1000 for every reference to mandatory minimum sentences or police budgets you can find in my comments on the thread.
To help you out, here’s what I’ve written so far, “No as dumb:”
There is virtually no “private security” in Lowell, the city with the largest drop in crime during the 1990s, the period when the US experienced its large drop in crime.
I’m sure the mall cops managed to move around crime to outside the mall.
How would you know? You can’t even seem to repeat back to me the ideas I’ve expressed when they’re sitting on the screen in front of your eyes.
July 20th, 2009 at 10:37 pm
“Lexus doesn’t control things like Mercedes does.”
Mercedes has a really old school way of doing things, but they inspire trust. Having an old car, my maintenance issues are far from normal. And most of the mechanics weren’t born when this car was built. They’ve never even seen a cartridge style oil filter. Thus, my need for a new crankshaft, among other things. Suffice it to say, my 2.3 liter engine is now about 2.5 liters and has kick ass custom machined pistons with custom fitted rings. So now the car has the custom hot rod changes it always wanted. But that car was a 1976 factory built sedan that could do 130 mph and be rock solid stable. I’ve done it, and it blew my mind. And I did it before any repairs. Now, I would have to find a track to see what it can do. I certainly don’t need more contact with the police. It also blew my mind that nobody caught me. The statute of limitations is way gone now.

Sensitive little thing, aren’t you?
You mentioned “community policing” which I assume involves individuals policing and reporting suspicious activity in their own neighborhoods. You do understand that this is essentially private protection? It is assumed that only the rich can afford private protection, but in fact the poor can provide the same protections by volunteering their own time which is worth less comparatively. Opportunity cost is the term, for the mentally impaired (such as yourself).
There is virtually no “private security” in Lowell, the city with the largest drop in crime during the 1990s, the period when the US experienced its large drop in crime.
You just said the mall has security. Has the security at the mall remained entirely static in this period? I’m not sure where you are going with this. It’s entirely plausible that surrounding communities used more private protections and Lowell received indirect benefits.. The spillover externalities you liberals so commonly cite as evidence that we must have government providing protection services. I’m guessing Lowell did far more than just stand idly and community watches are the large driver in increasing levels of protection as they are in most communities.
July 21st, 2009 at 9:23 am
There is no reason to think that the decline of crime rates is a result of better law enforcement. More likely it is due to demographic factors (e.g. Freakonomics).
July 21st, 2009 at 10:45 am
Confusing community policing with private policing seems like a mistake. Yeah, I could see where the instinct to lump them together comes from, but on important metrics they are different. First, community policing can be effective independently of income level so that’s a good thing for a progressive. Second, it doesn’t require armed private personnel, which I think most people would agree add risk in their own way. Third, it directly advocates against isolated communities, which stands in direct opposition to a significant sector of prviate security (so we have to choose which one is really effective). And fourth, community policing is a public policy that we can instruct our public officers to pursue. The policy that we would choose to encourage more private security officers would be obviously much different. As far as you are arguing with Joe, for example, lumping them together is just not sensible.

Nope. “Assume” makes an ass out of you. Period.
Look it up, find out what you’re talking about, and get back to me.
Seriously, you’re holding forth on the causes of the decline in crime, and insulting other people’s knowledge and intelligence, and you don’t even know what community policing is?
I’d feel bad for you, if it weren’t for the fact that your insufferable arrogance makes your embarrassment fun to watch.
Lowell doesn’t have a mall. I used the “mall cop” example to make a point, which apparently eluded you, about the effect of private security on crime.
I believe you.
Yes, they did. They implemented a strategy of community policing (why don’t you look that term up?), and staffed up the number of beat cops by tapping into federal grants like the COPS program.
COPS program, “No as stupid.” Ever heard of it? Care to take a guess what the C stands for?

July 21st, 2009 at 1:51 pm
How is this so fucking hard for you to understand. I will repeat is again community watches are private policing.
Rich people have very high opportunity cost for their time. It is better for them to hire someone else to patrol their neighborhood or watch the entrance to their property than to do it themselves.
First, community policing can be effective independently of income level so that’s a good thing for a progressive.
Poor people on the other hand (for example people from dumbfuck Lowell) don’t have particularly high opportunity cost for their time and reap larger rewards for patrolling themselves. They are still giving up a resource (their own time) in exchange for better, more focused, and more effective policing.
Both are private, and have provided a much larger decrease in crime than police departments and legislative mandates.
Second, it doesn’t require armed private personnel, which I think most people would agree add risk in their own way.
Less than 10% of private security guards are armed. Most have no more power than that of simple citizens arrest. Shootings per confrontation in private security are an order of magnitude less common than among public police.
