BEFORE THE CRIME: Understanding Crime

🎬 You've seen this scene a hundred times…

A police car pulls up.

🚨 Lights flashing.

👮 Officers jump out.

🚧 Crime-scene tape goes up.

🕵️ Investigators start looking around.

We've all seen some version of this in movies, television and true-crime documentaries.

But here's something you might not have thought about:

The police don't actually know that a crime has happened yet.

A suspicious scene isn't automatically a crime scene.

A person lying unconscious might have been assaulted… or suffered a medical emergency.

A broken window might mean burglary… or an accident.

A body might mean murder… or something completely different.

The scene is only the beginning.

🧠 Think About It

Think about your answer before revealing the explanation.

🎯 What You'll Learn

By the end of this lesson, you'll understand:

• What makes something a crime

• The difference between crime and deviance

• Why laws and circumstances matter

• Why investigators must establish what happened before deciding who did it

⚖️ Crime Means Breaking Criminal Law

A crime is behaviour that is prohibited by criminal law and can result in a criminal penalty.

That can include an act, and in some circumstances a failure to act where the law creates a duty to act.

Examples:

But here's the important distinction:

Something can be bad without being a crime.

Something can be harmful without being a crime.

Something can be socially unacceptable without being a crime.

💡 KEY IDEA

Crime = behaviour defined by criminal law as an offence.

Being immoral, rude, selfish or unpopular does not automatically make something criminal.

👀 Crime vs Deviance

These two words are often mixed up.

Crime → breaks criminal law

Deviance → breaks social norms or expectations

A person behaving strangely might be considered deviant without breaking any law.

Someone stealing a car has committed a crime.

And sometimes?

Behaviour can be both.

👉 ROOKIE TIP

Crime and deviance can overlap, but they are not the same thing.

You'll come across the word deviant from time to time in criminology and true-crime discussions. It simply refers to behaviour that goes against accepted social norms - it doesn't automatically mean criminal.

🌎 Crime Depends on Time & Place

Criminal laws aren't identical everywhere.

They can also change over time.

So when looking at an alleged offence, three questions matter:

📍 Where did it happen?

📅 When did it happen?

⚖️ What law applied at the time?

Context can completely change how behaviour is treated under the law.

👁️ INVESTIGATOR'S EYE

Where → When → What law?

Never assume the legal answer without checking the circumstances and the law that applies.

🕵️ Before “Who Did It?”

True crime loves the question:

“Who did it?”

But investigators need to work backwards first.

This is one of the most important habits we'll develop throughout Rookie Recruit:

Don't turn a suspicion into a fact.

You'll hear investigators talk about “establishing the facts” or “establishing what happened.” That's the job before anyone starts pointing the finger.

🧩 Rookie Recruit Takeaway

Crime isn't simply something bad, shocking or harmful.

It's behaviour that falls within a criminal offence defined by law.

And when you're looking at a suspicious situation, remember:

Establish what happened before deciding who did it.

We know what crime means.

But who actually studies crime and what are they trying to understand?

Next up:

What Is Criminology? ...

🎬 You've got a crime. Now zoom out.

A police investigation usually focuses on a particular event:

Who? What? When? Where? How?

Criminology asks some bigger questions:
Why does crime happen? Who is affected? What patterns can we find? And what might prevent it?

And this is where things get interesting.

Why does crime happen? Who is affected? What patterns can we find? And what might prevent it?

📚 What Is Criminology?

Criminology is the study of crime, criminal behaviour, victims, and society's response to crime.

It draws on areas such as psychology, sociology, law, economics and social science to help us understand crime.

🔍 Criminology Looks at the Bigger Picture

Different questions. Same subject: crime.

👉 ROOKIE TIP

Criminology ≠ criminal investigation.

An investigator may focus on solving a particular crime. A criminologist looks at crime on a much broader scale.

It's Not Just About Criminals

So criminology isn't simply:

“Why are criminals bad?”

In true-crime language, you might hear people talk about “the offender” as though that person is the whole story. Criminology takes a step back and asks what else is happening around the crime.

It's much bigger than that.

🔎 LOOK CLOSER

Criminology can examine offenders, victims, places, society and the justice system — not just criminals.

Crime Doesn't Have One Explanation

There isn't a single “criminal formula.”

Criminologists may examine combinations of:

🧬 Individual factors • 🏠 Family and upbringing • 🏙️ Environment • 💰 Social and economic conditions • 🚪 Opportunity

One factor rarely explains an entire crime:

This is why criminologists often talk about risk factors rather than simple causes. A risk factor may increase the likelihood of offending, but it doesn't mean someone will definitely commit a crime.

📊 Criminology Uses Evidence

Criminologists don't simply guess why people offend.

They can examine:

Crime statistics • Victimisation surveys • Court records • Interviews • Historical data • Research studies

The aim is to identify patterns, relationships and explanations that can be studied and tested.

In other words, it's not about coming up with a good-sounding theory and calling it a day. The evidence has to back it up.

🧠 Think About It

Imagine your town suddenly experiences a sharp increase in burglaries.

What else would you want to know?

Think about your answer before revealing the possibilities.

🧩 Rookie Recruit Takeaway

We've established what criminology is and how it differs from criminal investigation.

Criminology looks beyond individual crimes to examine offenders, victims, places, society and the justice system.

It uses evidence to look for patterns, relationships and explanations.

Coming Up Next ➡️

We've established what criminology is.

But that leads to a much bigger question:

Why does crime exist in the first place?

Next, we'll look at the many factors that can influence criminal behaviour and why there is rarely one simple answer.

Next up:

Why Does Crime Exist ...

🎬 Two people. Similar beginnings. Very different outcomes.

Imagine two people growing up in the same neighbourhood.

Similar schools. Similar opportunities. Similar surroundings.

One eventually becomes involved in crime.
The other doesn't.

So what made the difference?

That's the million-dollar question and criminology doesn't have a single answer.

There isn't one magic answer. Criminologists look at a combination of factors that may influence whether and how crime occurs.

Crime Has Many Pieces

Crime can be influenced by factors involving the:

Important: None of these automatically makes someone a criminal.

👉 ROOKIE TIP

A risk factor is not a prediction.

Being exposed to a particular factor does not mean someone will become involved in crime.

🚪 Opportunity Matters

Sometimes the circumstances surrounding a crime are just as interesting as the person committing it.

Think about two cars:

🔐 Car A: Locked, alarm active, parked in a secure area.

🔓 Car B: Unlocked, keys visible, parked somewhere isolated.

The opportunity is very different.

That doesn't mean everyone who sees Car B will steal it.

It simply shows why criminologists study situations and environments, as well as people.
In true-crime language, you might hear investigators talk about an opportunity or an opportunity for offending. It doesn't explain who committed the crime it helps explain why the circumstances may have made the crime possible.

🔎 LOOK CLOSER

Sometimes the question isn't just “Who would commit this crime?”

It's also “What made this crime possible?”

Nature, Nurture & Environment

You've probably heard the old argument:

Nature vs Nurture

In reality, human behaviour is rarely that simple.

These factors can interact in complicated ways.

There is no “criminal gene” that determines someone will become an offender.

That's an important distinction: influence isn't destiny. A person's background or biology may be part of the picture, but it doesn't come with a label saying future criminal.

⚖️ Understanding Isn't Excusing

This distinction is important.

Criminologists try to understand why offending occurs.

That doesn't mean they are saying the behaviour was acceptable.

⚠️ REMEMBER

Understanding why ≠ excusing what happened.

Explaining behaviour and justifying behaviour are two completely different things.

Put the Pieces Together

Imagine a person commits a burglary.

Instead of immediately asking:

“What's wrong with this person?”

A Criminologist Might Ask...

🧠 Think About It

What combination of factors might help explain this burglary?

Think about your answer before revealing the explanation.

🧩 Rookie Recruit Takeaway

Crime rarely has a single cause.

Understanding criminal behaviour means looking beyond the offender and considering the person, their circumstances, their environment and the opportunities around them.

Coming Up Next ➡️

We've explored why crime can happen.

Now let's look at the many different forms it can take.

Next up:

Types of Crime ...

🎬 One crime doesn't look like another

Picture these headlines:

	“Bank robbed at gunpoint.” “Business loses millions in fraud.” “International drug network dismantled.” “Cyberattack exposes customer data.”

They're all crimes but they're obviously very different.

Same word. Very different ball game.

That's why crime is divided into categories. It helps investigators, criminologists and the justice system describe what they're dealing with.

Violent Crime

Crime involving violence, the threat of violence, or harm against another person.

Not every violent crime causes serious physical injury, and the exact legal definition varies by jurisdiction.

👉 ROOKIE TIP

Violent crime doesn't always mean someone was physically injured.

The threat or use of violence can be enough for an offence to fall into this category.

You'll often hear true-crime shows describe a violent incident as “an act of violence” or say that someone was “threatened with violence.” The exact offence still depends on the circumstances and the law.

Property Crime

Here, the target is property rather than a person.
A break-in is a common everyday term you'll hear in true crime. It usually refers to someone unlawfully entering a building, although the exact legal offence can vary.

Examples:

🔑 Theft • 🏠 Burglary • 🚗 Vehicle theft • 🔥 Arson • 🪟 Property damage

Nobody may be physically attacked, but the impact on a victim can still be significant.

Financial & Organised Crime

Some criminals don't need a mask or getaway car.
Sometimes the “crime scene” is an office, a bank account or a computer screen.

They use deception, money, businesses, technology or organised networks.

Organised crime involves groups working together to carry out criminal activity.

💡 DID YOU KNOW?

Organised crime isn't necessarily a street gang. Criminal networks can operate through...
businesses, financial systems, technology and international connections.

Cybercrime

Crime has entered the digital world.

Cybercrime involves computers, networks, digital devices or online systems.
You may also hear the term cyberattack used for an attempt to disrupt, damage, access or steal information from a computer system or network.

Examples:

🖥️ Hacking • 🎣 Phishing • 🔐 Data theft • 💳 Online fraud

And there's an interesting twist:

The offender and victim may be thousands of kilometres apart — and may never meet.

Crime Doesn't Always Fit One Box

Here's something to remember:

Crime categories can overlap.
In other words, one investigation can have multiple offences or involve several different types of criminal activity.

Imagine an organised criminal group hacks into a company's computer system and steals millions of dollars.

That could involve:

Organised crime + Cybercrime + Financial crime

🧠 Think About It

Why might the same criminal activity belong to more than one crime category?

Think about your answer before revealing the explanation.

🧩 Rookie Recruit Takeaway

Crime comes in many forms.

Violent • Property • Financial • Organised • Cyber

And these are only some of the categories you'll encounter as you explore the world of crime.

Coming Up Next ➡️

We've established that crime comes in many forms.

But here's the tricky part:

How do we know how much crime is actually happening?

Next up:

How Crime is Measured ...

📊 The number doesn't always tell the whole story

You've probably seen a headline like:

“Crime has increased by 20%!”

Sounds alarming.
That headline certainly knows how to grab your attention.

But before we accept that number, there are a few things we need to know.

What crime? Where? Compared with what? And how was it measured?

👮 Police-Recorded Crime

One of the main sources of crime statistics is police records.

These can tell us about offences that have been reported to police and recorded in official systems.

They can help identify:
This is the sort of information you'll often see behind the crime statistics mentioned in news reports and true-crime stories.

📈 Trends • 📍 Locations • 🕐 Patterns over time • 🔎 Types of offences

But there's a problem...

The Crime We Don't See

Not every crime is reported.

A victim might be:

😨 Frightened • 😔 Embarrassed • 🤷 Unsure whether an offence occurred • 🙅 Convinced nothing will happen

So some crimes never make it into official statistics.

This is known as the:

🌑 DARK FIGURE OF CRIME

Crime that occurs but is not reported or captured in official crime statistics.

You'll come across this term in criminology because it reminds us that what gets recorded isn't necessarily everything that happens.

Different Sources Tell Different Stories

Crime can be measured in several ways.

No single source gives us the complete picture.

More Reports ≠ More Crime

Imagine police records show that burglaries have increased by 20%.

Does that definitely mean 20% more burglaries happened?

No.
This is where context matters and it's one of the easiest things to lose in a dramatic headline.

The increase could be influenced by:

More reporting • Changes in recording practices • Changes in the law • Better detection • An actual increase in offending

🔎 LOOK CLOSER

Crime statistics need context.

A number tells us what was recorded. It doesn't automatically explain why the number changed.

Think Before You Believe the Headline

“Crime has increased by 20%!”

🧠 Think About It

What would you want to know before deciding what that statistic actually means?

Think about your answer before revealing the possibilities.

🧩 Rookie Recruit Takeaway

Crime statistics are incredibly useful but they aren't a perfect count of every crime committed.

Remember:

Reported crime ≠ all crime

You'll also hear the phrase “recorded crime” used in reports and news coverage. Remember that recorded crime refers to offences that have made it into the official recording system not necessarily every offence that occurred.

And the next time you see a dramatic crime statistic, ask:

“Where did that number come from?”

Coming Up Next ➡️

Numbers can tell us a lot about crime.

But what happens when movies, television and the media start telling us what crime looks like?

Crime Myths vs Reality ...

🎬 You've probably seen it on TV...

The detective walks into a room.

Takes one look around.
Spots a tiny bloodstain.
Runs a DNA test.
Interrogates the suspect.

Case solved. 🕵️‍♂️

It makes for great television.
In the real world, though, there's usually a lot less “case solved” and a lot more paperwork, waiting and checking the evidence twice.

But real crime investigation is usually far less predictable — and much more interesting.

Criminal ≠ Psychopath

The word psychopath gets thrown around a lot in true crime.

But psychopathy is a specific psychological concept — it isn't a synonym for criminal.

Criminal behaviour occurs across a huge range of personalities, backgrounds and circumstances.

⚠️ REMEMBER

Most criminals are not psychopaths.

Psychopathy and criminality are not the same thing.

DNA Doesn't Magically Solve Cases

DNA can be incredibly powerful evidence.

But finding DNA doesn't automatically tell investigators:
You'll often hear investigators and forensic specialists talk about DNA evidence or a DNA match. A match can be highly significant, but investigators still need to establish how that DNA got there and what it means in the context of the case.

Who left it → When it was left → Why it was there

DNA has to be identified, interpreted and considered alongside other evidence.

🔎 LOOK CLOSER

Evidence gives investigators information — it doesn't automatically give them the whole story.

Body Language

Investigators may pay attention to body language, facial expressions, posture, gestures and changes in behaviour during interviews and interactions.

But these observations are clues, not proof of deception.

A person can look nervous because they're frightened, confused, uncomfortable or simply under pressure.

Here's where the myth and reality can be very different:

Behaviour needs to be considered in context.
This is why the idea of “reading a suspect” can be misleading. Looking nervous or uncomfortable might raise a question, but it isn't a smoking gun proving someone is lying.

🧠 Think About It

Can you identify a liar simply by watching their body language?

Think about your answer before revealing the explanation.

True Crime Isn't the Whole Case

A documentary may be based on a real investigation, but you're still watching a constructed version of events.

Real investigations contain:

📚 Reports • 📋 Paperwork • 🧑‍⚖️ Legal processes • 🔬 Evidence analysis • 🕐 Long periods where seemingly nothing happens

Television has to turn all of that into an hour.
And let's be honest — “Detective spends six hours checking paperwork” probably isn't making the opening credits.

⚠️ REMEMBER

Entertainment tells a story. Evidence establishes what happened.

They're not necessarily the same thing.

Think Before You Believe

You've probably heard plenty of crime “facts” over the years.

Some are true.
Some are exaggerated.
Some are completely wrong.

When something sounds convincing, ask:
You'll hear plenty of confident claims in true crime with everything from “there was foul play” to “they were acting suspicious.” Treat those statements as claims until the evidence supports them.

“How do we actually know that?”

That question will serve you well throughout this entire course.

🧩 Rookie Recruit Takeaway

Crime is surrounded by myths, many reinforced by movies, television and even true-crime entertainment.

The best habit you can develop is simple:

Don't assume. Look at the evidence.

Coming Up Next ➡️

We've looked at crime, criminology, criminal behaviour, crime types, statistics and crime myths.

Policing & Society ...

🚨 Imagine you've just called the police...

Something has happened in your neighbourhood.

You make the call.

A police officer arrives.

But what happens next?

And perhaps more importantly - what exactly are the police there to do?

Police Do More Than Catch Criminals

Police work can involve:

🚨 Responding - emergencies and calls for assistance
🔎 Investigating - offences, missing people and suspicious circumstances
🛡️ Protecting - people, property and public safety
⚖️ Enforcing - laws and making arrests where appropriate
🤝 Preventing - reducing crime and working with communities

💡 DID YOU KNOW?

A police officer can spend an entire shift dealing with situations where no crime has occurred at all.

Police may respond to accidents, welfare concerns, missing people, disputes and emergencies.

Police Need the Public

Police don't work in isolation.

A huge amount of investigative information comes from ordinary people.

👀 A witness notices something unusual.
📞 A caller reports suspicious activity.
📹 A camera captures an event.
🗣️ A victim explains what happened.

Sometimes a tiny observation can become an important lead.

👉 ROOKIE TIP

You don't have to be a detective to provide a clue.

Something that seems insignificant at the time may become important when investigators put the pieces together.

Police Have Powers

Police have legal powers that ordinary citizens don't.

Depending on the circumstances and the law, these can include powers to:

But those powers come with limits and responsibilities.

Police actions can be governed by legislation, policies, procedures, courts and oversight bodies.

The exact powers and rules vary between jurisdictions.

⚠️ REMEMBER

Police power is not unlimited power.

Officers are expected to exercise their powers lawfully and are accountable for how those powers are used.

Police Are Part of a Bigger System

Police are only one part of the criminal justice system.

The exact structure varies around the world, but the principle remains:

Investigating a crime and deciding guilt are two different jobs.

What Would You Do?

A neighbour sees someone climbing through a window at a nearby house.

They don't know who the person is.

They don't know whether the person lives there.

They simply see someone climbing through the window and call police.

🧠 Think About It

Was that the right thing to do?

Think about your answer before revealing the explanation.

🧩 Rookie Recruit Takeaway

Police aren't simply crime catchers.

They're part of a much larger system involving communities, investigators, prosecutors, courts and corrections.

And remember:

A good investigation starts with information - not assumptions.

🕵️ Activity - Crime or Not? ...

🕵️ Activity - Spot the Clues

Homeowners are away on vacation.

Late one evening, their neighbour hears a loud crash coming from the house.

The neighbour looks outside but can't see anyone.

Concerned, the neighbour calls police.

When officers arrive, they notice the front door is ajar and enter the house to check that everything is okay.

This is what they find when they enter the living room.

Take a close look at the scene.

What do you notice?

There are 8 things that might be worth a closer look.

Don't try to solve the case yet.

Just look, think and observe, can you spot 8 clues?

⚠️ Remember: spotting something unusual doesn't mean you know what happened. It's a clue, not a conclusion.
