Man Jailed After Chilling Death Threats to Mary Lou McDonald and Garda Chief
A 29-year-old man from Dublin has been sentenced to prison for making shocking threats to kill Sinn Féin leader Mary Lou McDonald and Garda Commissioner Drew Harris. The court heard that the threats were posted online, including videos that graphically detailed the man’s violent intentions.

Richard McGreevy, of Rathfarnham, was sentenced to three years in prison at the Dublin Circuit Criminal Court, with the final 18 months suspended, for two charges of threatening to kill or cause serious harm.
Online Threats Sparked National Concern
McGreevy’s threats were posted in 2022 across multiple online platforms, where he identified himself and declared his intent to kill the prominent political figures. In one disturbing video, McGreevy held a carving knife to his throat and spoke about decapitation, directly referencing Mary Lou McDonald. Another video involved a hammer and contained further explicit threats to both her and Commissioner Drew Harris.
According to Garda evidence presented in court, McGreevy also attempted to send emails to political offices and engaged in threatening communication through multiple channels. Gardaí were alerted by security officials who flagged the content due to its violent and targeted nature.
Detective Garda Aoife Curley testified that McGreevy had “freely admitted making the videos” and said he wanted them to be seen by the intended targets. He also reportedly told gardaí that he would have “cut off [McDonald’s] head” if given the opportunity.
Judge Labels McGreevy a ‘Lonely Keyboard Warrior’
Judge Martin Nolan described McGreevy as a “lonely keyboard warrior” during sentencing, highlighting the isolated and obsessive nature of his actions. The court was told that McGreevy has no prior convictions and suffers from social anxiety, depression, and a schizoid personality disorder.
“He is a man who lived in the shadows of online platforms,” Judge Nolan stated. “His threats were disturbing and showed a clear intention to instil fear in public figures. In today’s society, such actions cannot be tolerated, even when carried out from behind a screen.”
The judge took McGreevy’s mental health issues into account but stressed the seriousness of his offences. The partial suspension of his sentence was made on condition that he engage with mental health services and not contact the victims.
Victims Notified and Provided Security Advice
Both Mary Lou McDonald and Drew Harris were informed of the threats. McDonald, who represents Dublin Central, is a high-profile political figure and frequent target of online abuse. The Sinn Féin leader was reportedly shaken but defiant following the threats.
While there was no direct contact made with either of the victims, Gardaí treated the threats with utmost seriousness due to their specificity and the weapons displayed in the videos. Security advice was issued to both individuals as a precaution.
A source close to McDonald said: “She is aware of the situation and is grateful to the Gardaí for the swift handling of the case.”
A Reminder of Growing Online Abuse
The case highlights the rise in online harassment and threats targeting public figures, particularly women in politics. Several Irish politicians have spoken out in recent years about the toxic and dangerous abuse they receive on social media and other digital platforms.
Legal experts say the case sets a precedent for how online threats will be treated going forward. As more individuals rely on digital channels to harass, intimidate or threaten, the courts are increasingly demonstrating a willingness to impose custodial sentences.
One legal observer commented: “This isn’t just about freedom of speech—it’s about protecting the safety of individuals who serve in public office. Threats, no matter how ‘virtual’, can have real-world consequences.”
Moving Forward: Mental Health and Accountability
McGreevy’s sentencing reflects a balanced judicial approach: one that recognises the role of mental illness while firmly asserting accountability. He will serve 18 months in custody and must comply with court-ordered mental health support following his release.
As Ireland continues to grapple with the intersection of online behaviour, mental health, and public safety, this case is a stark reminder of the importance of vigilance—and the consequences of digital threats.
