Criminologist urges caution over Nonthaburi school shooting

A criminologist has warned against drawing quick conclusions about the motives behind a school shooting at Debsirin Nonthaburi School in Bang Kruai district, Nonthaburi, which left many people injured and dead.

The incident involved a Mathayom 2 male student, who opened fire on fellow pupils and teachers inside the school. Details of the suspected gunman's motive have not been confirmed by authorities.

Speaking on 7 August, criminologist and academic Ajarn Trin Phothiraksa said Thailand needed to learn serious lessons from such attacks, but stressed that claims about mental illness, bullying, resentment towards teachers or violent games should not be treated as fact without evidence.

Motive and risk factors must be separated

Trin said behavioural criminology distinguishes between a motive and risk factors. Bullying, family problems or mental health difficulties may be relevant factors, he said, but do not automatically lead a person to carry out a shooting.

He said information known so far pointed to several possible issues, including long-term bullying, alleged harassment by a group of students, a dispute involving a girl who reportedly complained to a teacher, and the student's reported viewing of overseas murder and mass-shooting videos on YouTube.

However, he said these were only possible explanations and should not be treated as established until properly investigated. The gunman died after the incident.

Trin also questioned why people in the gunman's household had been killed if his intended grievance was against people at school. He said it was an unusual aspect of the case and that outsiders could not know the offender's state of mind at the time.

Calls for metal screening and school psychologists

The weapon was owned by the student's grandfather, raising questions about gun storage and access by children. Trin said cases in which young people use firearms belonging to parents or relatives as weapons or for threats were a repeated warning for families.

He proposed metal detectors and weapons screening at places with large numbers of people, including schools, hospitals and cinemas, rather than restricting such systems to airports, Government House and parliament.

Citing figures previously reported by the Ministry of Social Development and Human Security, he said offences against life and bodily integrity committed by children and young people rose about 58.7% between fiscal years 2019 and 2023. Weapons-related cases rose about 92.1%, with most offenders of secondary-school age.

Trin said schools should have psychologists and counselling rooms, while teachers should speak with pupils and parents on both sides when bullying is reported. He added that games themselves were not inherently to blame, though violent content could act as a trigger for children who were already vulnerable.

Makes no difference to the deceased victims what their killer's motives were... they're still dead.

What we can say quickly is they died because the alleged perpetrator (ha!) had easy, quick access to a gun.

FULL STOP.

That's a telegraph term for you young ones not acquainted with 19th century tech terminology. 🤗

Thailand needs to review it's gun laws and guns should have to be stored in proper gun lockers with respsonseability on the gun owner as this is law in NZ and many countries, I've seen kids with dad the cops gun carried under the bike seat and know of people who have bought stolen guns through a policemans GF

  1. A potential lack of parenting. Or parents who are absent or lacking any parenting skills. Don't have kids if you can't look after them. Period.

  2. The grandfather was not cautious with his guns. He needs to be charged and imprisoned for the rest of his life.

  3. Even if the problems this piece of crap kid had were known, the extreme lack of mental health access here could have prevented anything being done about it.

  4. The extreme weakness that comes from the practice or face means that even if the bullying was reported, there may have been no consequences. Likewise it might have prevented counseling of the creep himself. One of the many consequences of a predominantly tribal culture. In my opinion, of course.

Just more ignorance from one of the most pathetic men in the history of Thai politics, who happens to be leading this nation into oblivion, right now.

How this goon ever rose to this position says alot about how broken the system is here.

No, you're partly not right.

It is indeed important to know why this boy needed a gun to solve his problem, no matter where the gun was nor to whom the gun belonged.

It's important to learn from this incident how to prevent similar cases in the future. Counselling rooms and private talk with a teacher in provided school areas is also important.

For the victim's families it might be even important to know why it happened.

There's a HUGE problem having Thai teachers do anything other than teach (that ability is still out for judgement). None of these people have the street smarts or brains to deal with issues.

Also getting parents to come in is a dream.

Hiring counselors would be go but the ones they will get are bottom of the barrel.

Setting up detectors is probably the best way although if someone wants to get something in they will

You are right.

Unfortunately, no matter how much discussion or announced well meaning initiatives to try and understand and prevent such incidents happening again, the reality is that there will be a lack of enforcement over any new regulations and little follow through on initiatives such as counseling.

In my experience, in Thailand if it’s not a quick fix, lessons learned from incidents such as this are quickly forgotten.

At least, so far, no one has suggested that the solution is to start giving teachers guns. That course of action espoused in a country that shall not be named is absolute lunacy.

I agree- and we all know that TIT- so the right thing may be said but in reality very little will change even when the reason for this tragedy is known

This was not a crime, it was stress related according to Anutin:

Not a crime ? Really ? I find it hard to believe anyone would say this. It is a horrific crime whatever the underlying circumstances/motives.

# 2 line - my thai guy at work yesterday told me the kid killed both the grandpa and grandma at home first before he went to the school - so the grandpa has already paid the price if this is the case

You are correct. Had he survived he should have been tried and convicted of aiding the crime.

Getting parents involved here would take some extreme doing, seeing a majority of the kids don't have an active father in their lives, and getting the farmers to come in to do anything besides picking their children up after school would be another problem.

At my daughter's school, talking with the supervisor, she told me many of the kids have no dads around at all, and a lot are raised by grandparents, with the moms elsewhere working. I've seen this all the time I've lived here when I pick up my daughter at school.

Granted, that way it's hard to know all of what's going on in certain households, but when you spend a lot of time in the village, going to funerals and such, you see who's taking care of the kids. What my daughter learns at school is also minimal compared to what she will back home. They have the Thai pride with some things, but the learning is way behind.

It's always just another issue with "face". You "lose face", so you want to kill. You can't "get face" so you want to kill. You can't report the kid for behavioral issues or "the family will lose face". The kid can't ask for help or "he'll lose face". It's the most ridiculous thing I have ever witnessed, and instead of being a force for good, it always ends up being a force for bad in any society that makes "face" their priority.

I don't think describing it as "not a crime" was appropriate.

The article did explain that because "the suspect died during the incident. Consequently, no criminal proceedings can occur regardless of his precise age. Legal specialists distinguish between the commission of an offence and the criminal responsibility of the offender. Against that legal background, the Prime Minister’s remarks are understood as referring to criminal liability rather than the legal status of the killings themselves" but I think that explanation would be lost on those griefing and the comment would have been better unsaid.

I used to be in charge of firearms licensing for a UK police force. Massive effort was put into background checks, demanding security measures such as lockable cabinets, and regular monitoring of behaviour. I even (temporarily) removed the certificates and possession of firearms from a serving police officer having marital problems.

Introduction of similar measures in Thailand coupled with effective enforcement would control both the legal possession and the illegal market in firearms. Unfortunately whilst adequate laws exist, I don’t have faith in enforcement being applied any time soon.

All good points.

Current Thai gun law does not specify that guns / ammunition must be kept in a suitably secure manner in the home.

Agree 100%. This was my immediate reaction. A school must be a safe place for everyone. If that means gun control, so be it!!

Unless you were routinely removing the license of parents with teen kids, your checks would have been worthless in this case.

Unfortunately true. Reliance on "perfect" parents is unrealistic.

"He proposed metal detectors and weapons screening at places with large numbers of people, including schools, hospitals and cinemas, rather than restricting such systems to airports, Government House and parliament."

Besides the costs of metal detectors, etc. to be borne by the tax payer, why should I be inconvenienced at the hospital so that Jimmy next door gets to keep his gun.
