Isaac Newton famously wrote “if I have seen further, it is by standing on the shoulders of giants.” Academic progress is always iterative and builds on the work of others, and a key component of academic culture is proper citation & attribution. It would be a travesty to let LLMs destroy that.

Or, in fact, not really a news story at all. I don’t believe at all that this was nationally important and certainly not “third on the BBC 6 o’clock news” important as a story. Cofnas started all of this because he’s a racist and the media ran with it.

• IRISH NETWORK AGAINST RACISM
INAR Statement on the death of Mr Yves Sakila: Monday 18 May 2026. Dublin.
The Irish Network Against Racism (INAR) is very concerned about the news that a man, believed to be Mr Yves Sakila, has died from suspected asphyxiation following his apprehension for an alleged shoplifting incident in Arnotts in Dublin on Friday 15 May. Nobody deserves to die for being suspected of shoplifting. Something clearly went terribly wrong. News of the tragedy is doubly shocking as some newspapers have reported that Mr Sakila is said to have "become unresponsive" after Gardai arrived on the scene.
A very disturbing 4m44s video has since emerged which appears to show the man on the ground being subdued by several men, who appear to be security guards and management at Arnotts. One of the men is seen to shift his weight onto his knee to drive it into the neck and head region of the subdued man. The man on the ground is heard shouting in distress as several men are kneeling on his body and the men shout several times for him to "stay down" while holding his neck and pinning his body to the ground with their combined weight. By the end of the 4m44s video we have seen, the man appears motionless. Gardai do not appear to have arrived on the scene at this stage.
Shane O'Curry, Director of INAR said "At INAR we are extremely disturbed by the reports of the incident, and we extend our sincere condolences to the family and friends of Mr Sakila. We are very concerned that this case appears to have the hallmarks of a case of excessive use of force. The death of a black man in such circumstances is extremely worrying, and we urge the authorities to thoroughly investigate all of the circumstances leading to this man's death, in order to ensure minority ethnic community confidence in the criminal justice system."

"The reason we have a notion of genocide, and a convention on genocide, is to define certain actions as always and definitively wrong" - Timothy Snyder, "the President speaks genocide" open.substack.com/pub/snyder/p...
Article III of the Genocide Convention makes it clear that not only the person who issues the genocidal order is guilty. Genocide itself is of course a crime, where genocide means the intent that Trump expressed, and actions such as killing members of a group, causing members of a group serious harm, or “deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part” -- which would of course include actions such as destroying access to energy or water. But also defined as a crime are conspiracy to commit genocide, incitement to commit genocide, attempts to commit genocide, and complicity in genocide.
