How to commit the perfect crime
There is a certain perverse pleasure in contemplating the perfect crime.
You can apply your ingenuity to the hypothetical issues of choosing a target, evading surveillance and law enforcement, dealing with contingencies and covering your tracks afterward. You can prove to yourself what an accomplished criminal mastermind you would be, if you so chose.
The perfect crime usually takes the form of a bank robbery in which the criminals cleverly bypass all security systems using neat gadgets, rappelling wires and knowledge they’ve acquired over several weeks of casing the joint. This seems to be an ideal crime because we can applaud the criminals’ cunning, intelligence and resourcefulness.
But it’s not quite perfect. After all, contingencies by definition depend on chance, and therefore can’t ever be perfectly thought out (and in all good bank-robber movies, the thieves either almost get caught or do). Even if the chances of being caught are close to zero, do we really want to call this a perfect crime? The authorities are likely to take it very seriously, and respond accordingly with harsh punishment. In this light, the 0.001 percent chance of getting caught might not seem like a lot, but if you take into account the severity of punishment, such crimes suddenly seem much less perfect.
In my mind, the perfect crime is one that not only yields more money, but is one where, if by some small chance you did get caught, no one would care, and the punishment would be negligible.
So, with this new knowledge how would you go about it?
First, the crime would need to be obscure and confusing, making it difficult to detect. Breaking a window and stealing jewelry is too straightforward. Second, the crime should involve many people engaging in the same type of crime so that no one can point a finger at you. This is why looting, though easy to detect, is much more difficult to get a handle on than a single robbery. Third, your crime will need to fall under the shady umbrella of plausible deniability so that if you do get caught, you can always say you didn’t know it was wrong in the first place. With this kind of defense, even if the public cares, the legal system may let you off easy. Moreover, plausible deniability allows you to apologize in the aftermath and ask forgiveness for your “mistake.”
If you really want to go all out, do something you can spin in a positive light, and maybe even create an ideology around it. This way you can then explain how you’re actually on the side of progress. Say, for instance, you’re “providing liquidity” and “lubricating the market” and thereby helping the economy – even if it happens to be by taking people’s money. You can also resort to opaque and promising-sounding language to make your case; you’re “restoring equilibrium,” “eliminating arbitrage” and creating “opportunity” and “efficiency” across the board.
Basically, just bottle snake oil and tell them it will cure, rather than cause, blindness.
Something to avoid, on the other hand, is anything involving an identifiable victim with whom people can sympathize and feel sorry for. Don’t rob one little old lady blind, or any one individual for that matter. It’s part of human nature that we care so much about blue-collar crime, even though the average burglary only costs about $1,300 (according to 2004 FBI crime reports), of which the criminal only nets a few hundred. Crimes like burglaries are the least ideal crime: they’re simple, detectable, perpetrated by a single or just a few people. They create an obvious victim and can’t be cloaked in rhetoric. Instead, what you should aim for is to steal a little bit of money from as many people as possible—little, old or otherwise — it doesn’t matter, as long as you don’t reverse the fortune of any one individual. After all, when lots of individuals suffer just a bit, people won’t mind as much.
So, what is the ideal crime? Which activity is difficult to detect, involves many people, has plausible deniability, can be supported by an ideology and affects many people just a bit? Yes, I think you know the answer, and it does involve banks…
Seriously, what we have here is a problem with our priorities. We have tremendous regulations for what is legal and illegal in the domain of possessions and blue-collar crime. But, what about regulations in banking? It is not that I really think that bankers plan and plot crimes for a living (I don’t), but I do think they are continuously faced with tremendous conflicts of interests, and as a consequence they see reality in a way that fits their own wallets and not their clients. The recent turmoil in the market is just a symptom of this conflict of interest problem, and unless we remove conflicts of interests from the banking system, we are going to be part of a long stream of perfect crimes.

My latest book, The Upside of Irrationality, explores some positive and some negative ways that irrationality plays out in our lives.

It’s interesting that as you described the ‘Perfect Crime’ in more detail, I started to think about the numerous stories I’ve heard of Bank of America foreclosing on houses that were fully paid off… and that they’d never held a loan on. Then I just turned to banks in general. This is why I’m utterly fascinated by the concept of ‘corporate personhood’, which more often than not seems to grant privileges than responsibilities.
Finally, I agree that there is a tremendous difference between blue collar and white collar crime. Or, crimes of the ‘commoner’ versus crimes of the ‘privileged’ (As a thought exercise, compare the cost of, say, polluting the Gulf of Mexico with oil versus downloading a song from BitTorrent…)
Better still to do something that isn’t even a crime at all! Insurance comes to mind. Insurance premiums are supposed in some way to reflect the risk the the insured event will crystallise. All you have to do is to look at the wildly differing premiums for ostensibly the same risk (e.g. car insurance quotes for the same driver) to see that this is a very inexact science indeed. Just a couple of extra pounds from each insured person might seem to be a limited kind of harm to inflict, but a profitable one for the insurer”
For me, the perfect crime would also have to be quick. I don’t mind spending a few weeks casing a bank but I don’t want to spend decades building up a large institution. There’s a huge investment of both time and money without the guarantee of a payoff.
What would happen if people didn’t go for my scam?
The perfect crime is one that takes a minimum of effort, makes you very rich, carries a low risk of getting caught and can be accomplished quickly.
When I give Computer Security talks at work, I use the example of hacking a big corporation, versus trying to trick you out of your credit card number or SSN. I explain that, were I nefarious, I’d go for the latter, since I can target a million people as easily as I could one, leading to a better ROI for my time. Plus, it’d be small enough that I’d probably be able to do it once and get off relatively scott-free.
It’s a good launching point for how to protect yourself from such attacks, and explains why they’re so prevalent in our inboxes.
I know a guy who hacked a large credit card company. He got caught, gagged and offered a job. Would’ve been worth millions had he gotten away with it.
Basically, target someone to whom the illusion of security is worth more than the take.
I thought the answer was going to be internet piracy. I was way off!
You are clueless.
I study social dilemmas and I have found that conflict of interests is the main cause of virtually any sort of societal problem; including but not limited to the banking systems. I agree, we need to design social systems which are based on more realistic assumptions about human behavior.
I know this is completely off-topic but when I read the heading I just thought about this: The perfect crime requires perfect planning, a high possibility of being caught, makes your heart beat out of your chest when you commit it. Still it does not harm anyone at all. And if you ever get caught you do not even have to defend yourself because there is nothing to be defended.
So what can it be?
To me, the perfect crime was committed in 1974 by Phillip Petit, the high wire artist by walking on a wire between Twin Towers. The documentary Man on Wire tells how he and his friends did this incredible plan.
Bankers? What a boring crime it is what they do…
Great article. I used to ponder perfect crimes and clever scams often when I was younger.
And yes selling CDO’s on subprime loans was the most diabollically brilliant crime of the capitalist era. The most impressive part being how bankers twisted out of the repurcussions and shifted the debt onto the public balance sheet.
If you want a solution look to Australia. We have properly regulated banks which are very profitable and were basically untouched by the subprime crises.
I agree about the banks. I was also thinking about Poor Fiscal Governance. Not just banks, but governments that are unaccountable and cannot be made to be more efficient. Comming from an “emerging market” the Philippines has a lot of corruption, and it stems primarily from making the Cost of Justice too High.
“So, what is the ideal crime? Which activity is difficult to detect, involves many people, has plausible deniability, can be supported by an ideology and affects many people just a bit? Yes, I think you know the answer, and it does involve banks…”
I was going to make the clever joke, “What does pirating music and movies have to do with banks?”, but I see William already had the same idea. Illegal file-sharing is even less risky than illegal banking, and has much more popular support (e.g., I won’t be at all surprised if there are comments following this one defending internet piracy, and I WILL be surprised if there are comments defending illegal banking practices).
IBG and IBG/YBG are the best models. These are the I’ll be gone model and the I’ll be gone / you’ll be gone model. Both are take the money and run schemes that have short term benefits to an individual or cooperating individuals and long term detriments to others left holding the bag.
Compensation based on options that can be short term big money if long term results are ignored. IBG
Compensation that is overly generous gained by the cooperation af a compliant board, IBG/YBG
Underfunded pension plans, pension plans based on unrealistic return assumptions. IBG
A perfect crime would be a crime that no one notices and does not get reported or cannot be reported. E.g – someone stealing from a thief.
If you steal from a thief, at least one person will notice for sure. And he will do his best to find you.
If you want to commit the perfect crime, here’s how: next time you do your taxes, report all of your income minus 0.01$. Technically, it’s a crime, but nobody’s going to prosecute you for one cent.
Oooooohh, my heart goes HERE IT COMES, Elizabeth, IT’S THE BIG ONE!!! by squeaking up a piffling technicality that only an IRS computer would notice for the absolutely planet-shatteringly payoff of
ONE PENNY.
Geez, seriously get me a freakin’ pacemaker, I can’t stand the excitement.
Ever heard of the criminal who hacked a large bank and took out $0.01 from each bank account?
…He was helping improve the security flaws. =)
Reminds me of the old English rhyme:
The law locks up the hapless felon
who steals the goose from off the common,
but lets the greater felon loose
who steals the common from the goose
