Police Data-Mining Done Right
enharmonix writes "Courtesy of Bruce Schneier, it's nice to hear something good about data mining for a change: predicting and stopping crime. For example, police in Redmond, VA, 'started overlaying crime reports with other data, such as weather, traffic, sports events and paydays for large employers. The data was analyzed three times a day and something interesting emerged: Robberies spiked on paydays near cheque cashing storefronts in specific neighbourhoods. Other clusters also became apparent, and pretty soon police were deploying resources in advance and predicting where crime was most likely to occur.'"
"I'm losing my nerve," Benny said mournfully. "Six times this past year we've flicked into flash crowds, and three times I threw away everything I had because it looked like the cops had time to put us under riot control. Once I was right. Twice I was wrong. That's just not good enough." He braced himself. "I think I'll quit." There, he'd said it.
A hole in space. Larry Niven.
Are the police going to share the location information?
I might want to watch. Cops live!

Do they really need to spend thousands of dollars analyzing data to determine there's more crime around check-cashing stores on paydays?
I don't really tend to think in terms of the police having the job of preventing crime. I think there job should be to apprehend criminals who are involved in or have committed a crime. That said, I guess it is good if they have tools that better help them to schedule and plan enforcement. Like anything, it can be taken too far. I would think that what would separate 'good' data mining from 'bad' data mining would be transparency and over site in the process.
On a side note - I'm willing to bet that if someone had asked most street cops in that area - they wouldn't have needed software or data mining tools to tell you that cash checking places in bad parts of town, on pay days were areas of higher crime.
It's hard to believe that's how Micronians are made. Why don't we see it right now by having you both kiss one another?
The city that won the business intelligence award for data mining is Richmond VA, not 'Redmond'.

you come to one undeniable conclusion:
cop work is one of the most criticized, and yet at the same time vital, aspects of modern life
almost all the comments here have some sort of negative thought or smarmy remark on an aspect of this story. and yet a cop is the first person these same people will call upon and depend upon if they are ever victimized or robbed. and what are the cops doing? no, what are they actually doing? i'm not asking your paranoid distrustful hollywood-addled alter ego, i'm asking your cognitive ability to look at and perceive the reality of actual police work
typical human shortsightedness and lack of gratitude
it must be so thankless being a cop. you're there to protect people, and all they can do is reflexively depart negativity at you
humanity sucks. you are all so ungrateful
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
Not really. Jail time and such has almost no effect on changing criminal behaviour.
Possibly. Or maybe they are trying to prevent crimes.
The criminals are not worried about going to jail AFTER the crime is committed. But if there is a cop there at the moment they would have committed the crime, most criminals will not commit it.
Means
Motive
Opportunity
With a cop right there, the "opportunity" is removed. So no crime occurs. In general, the crime rate should go down because this isn't something that can easily be displaced. It seems to be tied to the area around a check cashing storefront. Increase the patrols in those areas and the crimes are not committed.
imho

Strategic and tactical placement of resources to maximize effect without resorting to profiling or harassing citizens is a good thing.
Which check-cashing place do you go to?
I cried real tears when Li Mu Bai died.
Now for all those computer/techie types, how many bugs or problems/issues seemed remarkably simple after you noticed/fixed them? How many times have you slapped your head and said "geeze, that was really simple."
Sometimes it just helps to have somebody checking up on your work, even if that "somebody" is an automated process or machine.

What about cops walking a beat? That's right, walking down the same streets over and over everyday. Walking a beat means getting to know the locals and the particulars of a neighborhood in a way that doesn't happen in a squad car. Gangs don't hang out on a corner if once an hour a cops walks by a says hello, but the neighborhood kids still can hangout and could even end up viewing that cop as part of their neighborhood. From a squad car, no relationship is established and any stationary pack of teens can look like a gang to a biased eye. You don't have to profile when you actually know the people you see, but if you are just cruising along looking at a sea of nameless faces, then ethnicity and clothing style are about all you have to go on. Profiling is almost inevitable without establishing officers with good personal knowledge/relationship with the locals.
We are all just people.
Actually, in many places they do. Beat cops and homicide cops often have somewhat amicable relationships with drug gangs so that they have informants when violent crimes happen. Narcotics cops are another issue, but they don't walk beats and it's rarely useful to arrest low-level players who are selling at street corners.
I really liked Jello Biafra's notion that communities could vote for the policemen who would walk their beat. In a country like the US with such a low voter participation rate, I don't think it could really work though.
