Truth Before Testing: Investigation Concludes with Manager's Confession

Not every workplace investigation ends with a polygraph examination. Sometimes, a thorough investigation and the weight of the evidence are enough for the truth to emerge.
In a recent investigation conducted by LieTech Polygraph & Forensic Services, several employees were initially identified for possible voluntary polygraph examinations following two separate cash-handling incidents that raised significant concerns.

As investigators analysed the documentation, interviewed those involved and identified inconsistencies, the investigation took an unexpected turn.
The manager voluntarily accepted responsibility before the scheduled polygraph examinations could proceed.

The Investigation
The investigation centred on two separate incidents involving cash deposits:

Incident 1: Cash amounting to R8,315.10 could not be accounted for after no proof of deposit or G4S collection could be established.

Incident 2: A deposit bag that had repeatedly been reported as deposited was later found still on the premises before eventually being collected by G4S several days later.
These incidents justified a comprehensive investigation and the preparation of focused polygraph examinations.

The Outcome
Before any examinations were conducted:
The manager admitted responsibility.
The bulk of the financial loss was recovered.
The manager elected to resign with immediate effect.
A request was made for the remaining outstanding losses to be deducted from salary and accrued leave pay, helping to minimise the employer's financial loss.
The remaining employees were no longer required to undergo polygraph examinations.

An Important Lesson
This case highlights an important principle often overlooked:
A polygraph examination is not a replacement for a proper investigation. It is one investigative tool that complements interviews, documentary evidence, audit trails, CCTV, access control records and forensic analysis.

A well-conducted investigation frequently leads to admissions long before formal testing becomes necessary.

The objective is never simply to administer a polygraph—it is to establish the truth, protect innocent employees, identify those responsible, and assist organisations in resolving matters fairly and professionally.

LieTech Polygraph & Forensic Services remains committed to conducting ethical, impartial and evidence-based investigations—always in pursuit of the truth.

📱 SAY GOODBYE TO SIM CARDS AS YOU KNOW THEM IN SOUTH AFRICA

South Africa is gradually transitioning from traditional plastic SIM cards to eSIM technology. While this shift is primarily about convenience and innovation, it could also become an important tool in the fight against crime.
However, one uncomfortable reality cannot be ignored.
The current RICA system has significant enforcement weaknesses.
Despite legislation requiring every SIM card to be registered to its lawful user, there have been repeated reports over many years of pre-registered or improperly registered ("open") SIM cards being sold through informal channels, including at taxi ranks, street vendors and some informal retailers. Criminals have exploited these weaknesses to help conceal their identities when committing fraud, extortion, kidnappings and other serious offences.
The problem is therefore not necessarily the legislation itself—it is consistent enforcement.
If eSIM technology is introduced alongside:
stronger identity verification,
stricter compliance by mobile operators and retailers,
regular audits,
severe penalties for fraudulent SIM registrations, and
closer cooperation between the telecommunications industry and law enforcement,
South Africa could significantly reduce the abuse of anonymous mobile numbers.
Technology alone will never stop organised crime. Criminals constantly adapt. But every layer of accountability makes criminal operations more difficult and increases the chances of successful investigations and prosecutions.
As a former law enforcement officer, I have always believed that we cannot arrest our way out of crime. We must also outthink criminals by using better technology, intelligence-led policing, digital forensics and effective legislation that is properly enforced.
The move towards eSIM technology is therefore a step in the right direction.
Now Government, regulators, mobile operators and law enforcement must ensure that the mistakes of the current RICA system are not simply carried over into the next generation of mobile communications.
Technology should make life easier for honest South Africans—and considerably harder for criminals. 🇿🇦

⚖️ EMPLOYING UNDOCUMENTED FOREIGN NATIONALS: WHAT EVERY EMPLOYER SHOULD KNOW

Government has intensified inspections across South Africa to identify employers who unlawfully employ undocumented foreign nationals. These inspections are being conducted jointly by the Department of Employment and Labour, the Department of Home Affairs and the SAPS.
This is not simply about immigration. It is about compliance with the law, protecting legitimate businesses, safeguarding workers from exploitation, and ensuring fair competition in the labour market.
Every employer has a legal responsibility
Before employing anyone, employers should verify that the individual is legally entitled to work in South Africa. This includes checking identity documents, passports, visas or work permits where applicable, and ensuring that these documents are valid and current.
Keeping accurate employment records is not merely good business practice—it is an important part of demonstrating compliance during inspections.
What if you discover an existing employee is undocumented?
Many employers are asking this question.
If an employer discovers that an existing employee does not have valid documentation, the answer is not to panic or dismiss the employee on the spot.
A responsible employer should:
✔️ Verify the facts and request proof of the employee's legal right to work.
✔️ Give the employee a reasonable opportunity to provide valid documentation if it exists.
✔️ Carefully document every step taken.
✔️ Follow a fair labour process before making any employment decision.
✔️ Seek professional legal advice where necessary, particularly in complex cases.
Employers should remember that labour legislation still applies. Acting unfairly can expose a business to labour disputes, while continuing to employ someone who has no legal right to work may expose the employer to enforcement action under immigration legislation.
Compliance protects everyone
Businesses that comply with the law should never be disadvantaged by those who knowingly ignore it.
Likewise, undocumented workers are often victims of exploitation—receiving below-minimum wages, working excessive hours, and having little protection because they fear reporting abuse.
Proper enforcement helps combat exploitation while protecting lawful employment opportunities.
Government also has responsibilities
Effective enforcement cannot focus only on employers.
Government must also:
Strengthen border management.
Improve the efficiency of visa and work permit processing.
Combat corruption and fraudulent documentation.
Target criminal syndicates involved in illegal immigration and labour exploitation.
Apply the law consistently and fairly to everyone.
The bigger picture
South Africa needs a labour market that is fair, lawful and competitive.
That means protecting jobs, supporting businesses that comply with the law, safeguarding vulnerable workers from exploitation, and ensuring that immigration and labour legislation are enforced consistently and without fear or favour.
The rule of law benefits everyone. Compliance is not optional—it is the foundation of a fair and sustainable economy.

🇿🇦 ILLEGAL IMMIGRATION, EMPLOYERS, AND LABOUR LAW: THE PART OF THE DEBATE MANY ARE MISSING 🇿🇦

President Cyril Ramaphosa's recent warning that employers who knowingly hire undocumented foreign nationals could face criminal prosecution has reignited a national debate.

For many South Africans, the issue is simple:

"If a person is in the country illegally, they should not be working."

While that may sound straightforward, the reality is far more complex because immigration law and labour law often intersect.

South African employers have a legal obligation to ensure that employees are legally entitled to work in the country. Ignoring this responsibility can expose employers to penalties, fines, and potentially criminal prosecution.

However, compliance with immigration law does not remove an employer's obligation to comply with labour law.

This is where many employers get into trouble.

An employer cannot simply discover a problem with an employee's documentation and immediately show that employee the door.

Labour law still requires fairness.

Employers should investigate the facts, verify documentation, allow the employee an opportunity to explain any discrepancies, and follow a fair process before making any decision regarding continued employment.

An employee's immigration status does not automatically remove all labour rights.

In some cases, employers have attempted to avoid labour disputes by placing pressure on employees to resign. This can create an entirely different legal problem known as constructive dismissal.

Constructive dismissal occurs when an employer makes continued employment so intolerable that the employee feels compelled to resign. In such cases, the employee may still approach the CCMA or a bargaining council and argue that the resignation was effectively a dismissal caused by the employer's conduct.

The safest approach for employers is therefore not panic, but process.

Employers should maintain proper records, conduct regular compliance audits, monitor visa and permit expiry dates, and ensure that all documentation remains current.

One practical solution is to make the right to work a continuing condition of employment.

Employment contracts should clearly state that continued employment is subject to the employee maintaining a valid legal right to work in South Africa and providing proof thereof when required.

Employers should maintain registers for:

✔ Work permits ✔ Visas ✔ Passports ✔ Permit expiry dates ✔ Renewal applications

This allows employers to identify potential problems before they become legal liabilities.

Where employees work under temporary visas or permits, it may also be prudent for contracts to align with the duration of the relevant authorisation. However, employers should be cautious about relying solely on automatic termination clauses and should still follow a fair process if an employee's work authorisation lapses or becomes disputed.

Employees also carry responsibilities.

Workers must ensure that their documentation remains valid, inform employers of changes to their status, cooperate with verification processes, and never submit fraudulent documentation.

The use of forged permits, false identities, or misrepresentation can expose individuals to serious criminal consequences.

Ultimately, the debate should not focus solely on undocumented workers.

The larger question is why some employers knowingly create demand for illegal labour in the first place.

If businesses knowingly employ undocumented workers because they can be paid less, dismissed more easily, or employed without labour protections, then enforcement must focus not only on the worker but also on the employer, labour brokers, document fraud syndicates, and corrupt officials who facilitate the system.

South Africa has a right to secure its borders, enforce its immigration laws, and protect employment opportunities for its citizens.

At the same time, the rule of law requires that employers act fairly, employees act honestly, and government enforce the law consistently.

The answer is not vigilantism.

The answer is lawful enforcement, responsible employers, accountable government, and fair labour practices.

Only then can immigration control and labour rights coexist in a manner that protects both South African workers and the integrity of our legal system.

🇿🇦 MADLANGA COMMISSION: THE REAL ISSUE IS BIGGER THAN ONE POLYGRAPH EXAMINATION 🇿🇦

The testimony emerging from the Madlanga Commission has sparked intense public debate.
For some, it is about Karl Sander.
For others, it is about a disputed polygraph examination.
But for many current and former police officials, investigators, intelligence practitioners, forensic specialists, and polygraph examiners, the issue is far bigger.
It is about accountability.
It is about institutional integrity.
It is about leadership.
And it is about whether South Africa is adequately supporting the specialised capabilities entrusted with protecting the rule of law.
Having been involved in the polygraph profession for many years, including both Basic and Advanced Polygraph Training, and having interacted with members of the SAPS Forensic Science Laboratory Polygraph Unit, I have witnessed both the strengths and challenges of this specialised discipline.
One fact should not be lost in the current debate:
Polygraph testing remains a valuable investigative and integrity-management tool.
For more than a century, law-enforcement agencies, intelligence services, military organisations, government institutions, and private-sector organisations around the world have continued to utilise polygraph because it contributes value when used correctly.
No professional examiner claims that polygraph is infallible.
No professional investigator should rely on it in isolation.
But neither should its value be dismissed.
Polygraph is not a crystal ball.
It is not a substitute for detective work.
It is not a shortcut to justice.
It is an investigative aid that can generate admissions, identify investigative leads, corroborate information, eliminate innocent persons from suspicion, and help focus investigative resources where they are most needed.
Polygraph is the science.
Polygraph testing is the art of applying that science.
The instrument records physiological data.
The science explains what is being measured.
The examiner applies professional interviewing skills, validated methodologies, question formulation, chart analysis, and investigative experience.
That is why examiner competence, integrity, training, and independence are so important.
Because behind every examination sits a human being.
A career.
A reputation.
A family.
And sometimes a future that may be influenced by the outcome.
The stakes are simply too high for anything less than excellence.
Unfortunately, the current debate has also exposed several uncomfortable realities that have affected specialised capabilities for years:
• Ageing equipment • Outdated software • Limited advanced training opportunities • Budget constraints • Loss of institutional knowledge • Reduced succession planning • Increasing bureaucracy and protocol restrictions
This is not a criticism of individual examiners.
Many dedicated professionals continue to perform highly specialised work under circumstances that are far from ideal.
The concern lies with the system.
How can government expect world-class results from specialised disciplines while failing to invest adequately in modern technology, training, examiner development, and quality assurance?
Technology evolves.
Research evolves.
Methodologies evolve.
Criminals evolve.
Specialised capabilities must evolve as well.
Another issue seldom discussed publicly is examiner independence.
Polygraph examinations must be conducted without fear, favour, prejudice, interference, or predetermined outcomes.
The examiner's responsibility is not to produce a desired result.
It is not to satisfy management expectations.
It is not to protect reputations.
It is to report findings honestly and professionally, regardless of where those findings may lead.
This becomes particularly important in rank-driven environments.
An examiner may be required to examine a senior officer who possesses significant authority, influence, and control over careers and resources.
In theory, rank should be irrelevant.
In practice, the reality can be far more complicated.
Integrity systems cannot function effectively if those tasked with protecting integrity fear becoming victims themselves.
This brings us back to the Karl Sander matter.
Whether one agrees with Karl Sander or not is almost beside the point.
The public is entitled to ask whether the process was fair, consistent, transparent, and beyond reproach.
Because confidence in any investigation depends not only on the outcome, but on the credibility of the process that produced that outcome.
Perhaps the greatest lesson emerging from the Madlanga Commission is this:
Institutions do not fail overnight.
They weaken gradually.
They weaken when specialist skills are neglected.
They weaken when training stagnates.
They weaken when technology becomes outdated.
They weaken when expertise is lost.
They weaken when warning signs are ignored.
And they weaken when those tasked with protecting integrity are not adequately supported.
South Africa has no shortage of talented investigators, forensic specialists, intelligence officers, polygraph examiners, and dedicated police officials.
What is needed is leadership willing to invest in those capabilities, modernise them, protect their independence, and ensure they remain fit for purpose.
The Madlanga Commission has opened a can of worms.
The real question now is whether government and police leadership have the courage to confront what is inside.
Because this conversation is no longer only about Karl Sander.
It is no longer only about one polygraph examination.
It is about the future of policing.
It is about accountability.
It is about specialised capabilities.
It is about institutional integrity.
And that conversation is long overdue.
🇿🇦 In the pursuit of truth, the tool remains valuable. The challenge is ensuring that the systems, leadership, training, equipment, technology, and support structures behind that tool remain worthy of the responsibility entrusted to them.

🇿🇦 KARL SANDER, WE SALUTE YOU 🇿🇦
For more than four decades, Karl Sander dedicated his life to serving South Africa and combating organised crime, often under difficult, dangerous, and politically sensitive circumstances.
Today, many current and former colleagues speak of a man who earned respect not through rank, political connections, or personal influence, but through hard work, experience, professionalism, and an unwavering commitment to his oath.
As testimony unfolds before the Madlanga Commission, South Africans are hearing allegations and evidence that raise serious questions about how honest investigators are treated when they refuse to compromise their principles.
The Commission will ultimately determine the facts.
However, if the allegations emerging before it are proven to be true, South Africans may be forced to confront an uncomfortable reality:
What happens to those who refuse to cross the line when corruption comes knocking?
One aspect of the testimony that has attracted considerable public attention is the fact that Karl Sander himself was subjected to polygraph examinations.
According to evidence presented before the Commission, Sander underwent polygraph testing during investigations into matters that ultimately placed him under suspicion. Yet the testimony has also raised questions about whether the same level of scrutiny was applied consistently to all individuals who may have had knowledge of, access to, or involvement in the matters under investigation.
This is where many South Africans are beginning to ask difficult questions.
If investigators are prepared to subject themselves to scrutiny, answer difficult questions, and undergo testing, should the same standards not apply to everyone?
Were all relevant individuals interviewed?
Were all potential suspects subjected to the same investigative standards?
Were investigative tools applied objectively and consistently?
Or were some individuals subjected to scrutiny while others appeared to escape it?
A polygraph examination is not proof of guilt or innocence. It is merely one investigative tool among many. However, when such tools appear to be applied selectively, legitimate questions arise regarding fairness, consistency, and the integrity of the investigative process itself.
The real issue is therefore not the polygraph itself.
The real issue is accountability.
No machine can replace ethical leadership.
No investigative tool can compensate for a lack of transparency.
No institution can maintain public trust if accountability is applied selectively.
At its heart, the Madlanga Commission is about far more than any single witness.
It is about whether honest public servants can perform their duties without fear of retaliation.
It is about whether investigators can pursue the truth wherever it leads.
It is about whether integrity is rewarded or punished.
Many current and former colleagues describe Karl Sander as a man who remained true to his oath despite immense pressure and challenging circumstances.
His reputation was not built overnight.
It was earned through decades of service.
To every police officer, investigator, detective, intelligence operative, prosecutor, and public servant who has chosen integrity over personal gain, who has stood firm when pressured to look the other way, and who continues to serve despite enormous challenges:
We see you.
We thank you.
We salute you.
🇿🇦 Karl Sander, we salute you.
Your service, sacrifice, professionalism, and commitment have not gone unnoticed.
"Integrity is doing the right thing, even when no one is watching."

Note: The Madlanga Commission is responsible for determining the facts and findings arising from the evidence presented before it. The questions raised above reflect matters of public interest and accountability that have emerged during testimony.

WEEKEND BEHIND BARS.

Another reminder that actions have consequences.

What initially started as an investigation involving approximately ten possible suspects was gradually narrowed down through interviews, verification processes, evidence analysis, and investigative follow-ups.

One particular suspect, from the outset, refused to undergo a polygraph examination. However, when confronted with certain evidence gathered during the investigation, the suspect ultimately decided to come clean and made verbal as well as written admissions relating to the matter. Supporting evidence was subsequently secured and the suspect was handed over to the South African Police Service for further investigation.

During the examination and investigative process, the suspect himself voluntarily provided self-incriminating information relating to transactions, individuals allegedly involved in the purchase of devices, and additional evidence which further assisted the investigation.

The suspect has furthermore reportedly undertaken to compensate the company for its losses by agreeing to sign over his provident fund as part of the restitution process.

While remorse, cooperation, restitution, and admissions may later be considered during legal proceedings or possible plea negotiations, justice must still take its course. Accountability remains essential, not only for the affected company, but also for every honest employee and every South African who expects fairness, integrity, and consequences for wrongdoing.
Investigations are not built on assumptions or intimidation. They are built on: • evidence, • timelines, • corroboration, • interviews, • digital analysis, • financial records, • behavioural observations, • and proper investigative procedure.
Too often individuals believe: • nobody will notice, • accountability can be avoided, • systems are weak, • or that silence will make problems disappear.

But the truth has a way of surfacing.
Sometimes investigations take patience. Sometimes evidence must be followed quietly, carefully, and professionally.

And sometimes, when the pressure of the evidence becomes too much, the truth finally surfaces.

A reminder to every employee, contractor, supplier, and individual entrusted with responsibility:
Integrity matters. Choices matter. And eventually… accountability arrives.

It may not happen immediately. But when the time comes — it is the time.

Corporate theft, fraud, dishonesty, and abuse of trust affect far more than balance sheets. They affect: • businesses, • innocent employees, • operational stability, • workplace trust, • and ultimately the broader economy.

A weekend behind bars has a way of changing perspectives very quickly.
Integrity still matters. Accountability still matters. And consequences must remain real.
