The conviction of a Serbian couple whose son killed nine classmates and a guard has sent a chill through Britain’s corridors of power. For the first time, parents of a school shooter have been held criminally responsible for their child’s actions. And in a nation still haunted by its own school massacres, the case is forcing a reckoning over how far parental liability should stretch under UK law.
Belgrade’s High Court sentenced the father to 14 years and the mother to three years for “aggravating the safety of the public” after their 13-year-old son carried out a meticulously planned attack using his father’s guns. Prosecutors argued the parents ignored clear warning signs: the boy’s obsession with violent video games, his isolation, and his possession of a ‘hit list’ of classmates. The verdict recognises a new principle: that negligence in securing weapons and monitoring a child’s behaviour can constitute a culpable failure.
Across the UK, the reaction has been visceral. On Merseyside, where a 17-year-old killed three young girls at a Taylor Swift dance class last July, campaigners argue that British law is too lenient on parents. Under the Firearms Act, it is an offence to fail to securely store a firearm, but sentences rarely reflect the catastrophic consequences. In the Serbian case, the father’s guns were kept in an unlocked wardrobe. In too many UK homes, shotguns are propped in cupboards, and hunting rifles rest on racks.
But the issue goes beyond gun cabinets. The Serbian parents were also convicted for failing to supervise a child they knew was troubled. This raises uncomfortable questions for British parents in an age of anxiety. When a teenager posts a manifesto, stockpiles knives, or writes disturbing poetry, where does parental responsibility end? The UK has no specific offence for neglecting to monitor a child’s mental state. The courts rely on general child cruelty laws, which require proof of “wilful neglect” rather than mere oversight.
Legal experts are divided. Some argue that criminalising parental failure would be a dangerous incursion into family privacy. “We cannot have a nanny state prosecuting every parent whose child goes astray,” says Dr. Helena Crawley, a criminologist at the London School of Economics. “The Serbian verdict is rooted in a specific cultural context. Here, the focus should be on better mental health support and tighter gun control.”
Yet the public mood is shifting. A recent YouGov poll found that 68% of Britons believe parents should be held legally liable for their children’s violent acts. The cases of the Plymouth shooter (who killed five in 2021) and the Manchester Arena bomber (whose brother was reportedly radicalised online) have stoked a sense that families must be part of the solution. Politicians are sensing the wind. The Home Secretary has ordered a review of parental responsibility laws, and a cross-party bill on “failure to prevent harm by a child” is being drafted.
The human cost is plain. In Serbia, the families of the victims say the verdict brings “symbolic justice” but cannot fill the empty seats. In the UK, the mother of one of the Merseyside victims told me: “If locking up parents stops just one other mother feeling this pain, then it’s a price worth paying.” It is a desperate plea from a society that has run out of answers.
The cultural shift is undeniable. We have moved from seeing school shootings as isolated American tragedies to a global crisis. And in this new landscape, the Serbian verdict represents a frontier: the extension of culpability to those who raise the monsters. Whether Britain follows suit depends on whether we believe parenting can be regulated by law, or whether the bond between parent and child remains a sanctuary the state cannot enter.
For now, the Serbian case stands as a warning. The guns were legal. The family was middle class. The son was, by all accounts, quiet. And the parents are now behind bars.
