Introduction
A street thief steals a wallet.
A cybercriminal steals millions of dollars.
A terrorist steals lives.
Different crimes. Different weapons. Different battlefields.
Yet, after more than three decades of working across military operations, diplomatic intelligence, and corporate investigations, I have reached one uncomfortable conclusion: they all think far more alike than most people realise.
Crime constantly changes its form. It adapts to new technology, new opportunities, and new societies.
What once required a crowbar can now be achieved with a laptop. What once demanded physical presence can now be executed from another continent.
But despite these changes, human nature remains remarkably constant.
Every day we are overwhelmed with crime statistics.
Vehicle thefts continue to rise, cyberattacks cost businesses billions of dollars each year, and headlines report violent offences, organised crime, domestic violence and politically motivated attacks across the globe.
It is easy to become overwhelmed by the scale of modern crime and believe we live in an era of complete unpredictability.
Yet once we strip away the headlines and statistical jargon, one simple question remains.
What do all criminals have in common?
Having spent decades analysing human behaviour rather than simply crime statistics, I have learned that the answer is rarely found in technology or complex algorithms.
It is found in human behaviour.
Every Criminal Searches for Empty Space
The first and perhaps most important characteristic shared by criminals is their ability to recognise and exploit vulnerability.
Military strategy teaches one fundamental principle.
You never attack where the defence is strongest.
You attack where resistance is weakest.
Criminals operate the same way.
A burglar walking down a suburban street rarely chooses the house protected by visible cameras, good lighting and attentive neighbours if the house next door has an unlocked side gate, overgrown hedges and an open window.
A cybercriminal rarely attempts to defeat sophisticated encryption if one employee is willing to click a malicious email attachment.
The technology changes.
The thinking does not.
Criminologists describe crime through routine activity theory, which argues that crime occurs when three elements come together: a motivated offender, a suitable target and the absence of an effective guardian. Remove one of those elements and the opportunity often disappears.
Data consistently shows that property crime remains one of the most common criminal offences worldwide.
What connects them all?
Opportunity.
A criminal is, above all else, a calculating opportunist.
Even violent offenders usually wait until a victim is distracted, isolated or unable to respond effectively.
Security is therefore rarely about force.
It is about removing opportunity.
Lock your side gate.
Store your vehicle keys away from your front entrance.
Control access inside your business.
These are not dramatic actions.
They simply eliminate the “empty space” criminals depend upon.
The Faces Change. Psychology Does Not.
If we examine who commits most offences, demographic research consistently points towards young adult males, particularly those in their late teens and twenties.
Across most countries, they account for most violent and property offences.
Why?
This phenomenon is because this stage of life often combines impulsive decision-making, a desire for new experiences, and limited risk assessment.
Female offenders remain statistically less likely to commit violent offences and are more frequently associated with fraud, deception and other non-violent crimes.
But age alone never explains criminal behaviour.
Throughout my investigations, I have consistently identified another common denominator.
Environment.
Many offenders grow up where violence, neglect, abuse or criminal behaviour becomes normal rather than exceptional.
When organised crime becomes the only visible path to status, wealth or belonging, criminal thinking begins long before criminal action.
People raised without healthy boundaries often learn survival before empathy.
Eventually the distinction between right and wrong becomes blurred.
Nobody Thinks They Are the Villain
Perhaps the most fascinating lesson from studying offender behaviour is this:
Very few criminals believe they are bad people.
During interviews and investigations, I have rarely encountered someone who simply admitted, “I chose to become a criminal.”
Instead, I heard remarkably similar justifications.
A cybercriminal who extorts a multinational company sees themselves as exposing weaknesses in a wealthy system.
An extremist convinces themselves they are serving a higher ideological purpose.
A street thief tells themselves the victim has insurance.
A fraudster believes the corporation can afford the loss.
Changing the story inside their mind becomes easier than accepting personal responsibility.
Psychologists describe the phenomenon as moral disengagement—a process through which individuals justify harmful behaviour while preserving a positive self-image.
The scale of the crime changes.
Psychology rarely does.
Whether interviewing a pickpocket or analysing organised crime, I have observed the same patterns.
Responsibility is transferred.
Blame is externalised.
The victim becomes invisible.
Technology Evolves. Deception Never Does.
Modern crime has unquestionably expanded into the digital world.
Cybercrime now costs the global economy trillions of dollars annually.
Artificial intelligence has accelerated phishing campaigns, deepfake scams and identity theft to an unprecedented scale.
Yet despite the sophisticated technology, the underlying tactic has barely changed.
It is still deception.
A hacker using artificial intelligence to impersonate a chief executive is fundamentally exploiting the same human weakness as a con artist knocking on someone’s front door fifty years ago.
Trust.
Technology merely increases the speed and scale.
The psychology remains identical.
The same principle applies to organised crime.
Whether laundering money, trafficking drugs or operating sophisticated online scams, criminal organisations simply industrialise the same behaviour.
Identify weakness.
Exploit trust.
Minimise risk.
Maximise reward.
This is why separating physical security from cybersecurity is increasingly dangerous.
Both are ultimately based on human behaviour.
A poorly positioned CCTV camera and a poorly configured network password represent the same vulnerability.
Different systems.
Same weakness.
How to Protect Yourself
After decades working in military environments, intelligence operations and corporate investigations, I have learned one lesson above all others.
Security is never luck.
It is a habit.
Criminals depend upon complacency, distraction and predictable routines.
If you genuinely want to reduce your risk, focus on simple disciplines rather than expensive technology.
Think like an opportunist
Walk around your property as though your objective were to enter unnoticed.
Where are the blind spots?
Which doors or windows would attract your attention?
Where are your vehicle keys?
Prioritise quality over quantity
One properly positioned camera capable of producing clear evidence is worth more than several cameras recording unusable footage.
Regularly audit your routines.
Within businesses, the greatest vulnerability is often convenience.
An unlocked rear loading dock.
A staff-only door left open.
Passwords shared between colleagues.
Criminals rarely succeed because they are brilliant.
They succeed because someone became careless.
Conclusion
Preventing crime has never been about predicting the future.
It has always been about understanding human nature.
There will always be individuals searching for shortcuts, exploiting dishonesty or using violence to achieve their objectives.
Our responsibility—as parents, business leaders, investigators and members of our communities—is not to live in fear.
It is to understand how criminals think before they act.
Once you recognise that every offender is searching for the path of least resistance, your objective becomes remarkably simple.
Remove the opportunity.
Increase the effort.
Raise the likelihood of detection.
Most criminals will simply move elsewhere.
After all, criminals spend every day searching for weakness.
Our job is to ensure they never find it.
