Madlanga Commission: Chaskalson explains how jammers block communications to Commissioner Baloyi

The Madlanga Commission of Inquiry received a technical briefing on the dangers of signal jamming during its session on 18 August 2026. Evidence leader Matthew Chaskalson explained the mechanics of the technology to Commissioner Sesi Baloyi, highlighting its use in both petty theft and major security breaches.

From Parking Lots to Police Raids

Chaskalson noted that many South Africans are already victims of basic jamming devices. These small tools are frequently used by criminals to block car remotes, leaving vehicles unlocked and vulnerable to theft without the owner's knowledge.

However, the testimony moved quickly to more sophisticated applications. Chaskalson revealed that advanced jammers can shut down entire mobile phone networks by targeting specific frequencies, a tactic that poses a direct threat to national security.

Commissioner Baloyi questioned whether these devices could be used to sabotage law enforcement. Chaskalson confirmed this risk, stating that jammers are fully capable of preventing police from intercepting vital communications during active investigations.

A Personal Encounter with Tech

In a lighthearted but telling moment, Baloyi remarked that Chaskalson seemed to be dealing with technical interference during his own presentation. The evidence leader admitted he had actually encountered two instances of small-scale jamming himself.

The commission is currently investigating allegations involving private entities that may have been posing as state agencies. These technical insights are crucial to understanding how unauthorized parties could disrupt official government functions.

Broader Context of the Inquiry

These hearings coincide with other explosive claims regarding high-ranking officials. Recent testimony suggested that suspended National Police Commissioner General Fannie Masemola was unfairly targeted during a tender probe, despite a lack of evidence linking him to any crimes.

As the Madlanga Commission continues its work, the focus remains on uncovering how state systems were potentially compromised by outside actors and sophisticated technology.
