Dr David Kelly, a UK Ministry of Defence biological weapons expert, was found dead in Harrowdown Hill woods, Oxfordshire, on 17 July 2003 after being publicly identified as the source who had told BBC reporter Andrew Gilligan that the Iraq WMD dossier had been "sexed up." The Hutton Inquiry (2003) ruled suicide by haemorrhage from a severed left ulnar artery compounded by co-proxamol toxicity and heart disease. A group of doctors challenged the findings from 2010 to 2015, arguing the ulnar artery wound could not have produced fatal blood loss, the co-proxamol level was sub-lethal, and there were no fingerprints on the knife. The Hutton Inquiry's 70-year document seal was later partially overturned. Verdict: partially true — the suicide ruling is contested by credible medical professionals, but no alternative account has been formally established.

EgyptAir Flight 990, a Boeing 767-300ER operating LAX-CAI via JFK, plunged into the Atlantic Ocean 60 miles south of Nantucket on 31 October 1999, killing all 217 people on board. The NTSB concluded in its 2002 final report that the crash resulted from the deliberate action of relief First Officer Gameel Al-Batouti, who was alone at the controls and said 'Tawakkalt ala Allah' (I rely on God) eleven times before and during the dive. Egypt's ECAA disputed the finding, attributing the crash to mechanical failure of the elevator/pitch-trim system. The dispute has never been formally resolved and reflects genuine national and investigatory disagreement.

Virginia Giuffre filed a civil suit against Prince Andrew on 9 August 2021 in the Southern District of New York, alleging battery and intentional infliction of emotional distress arising from alleged sexual abuse while she was trafficked by Jeffrey Epstein. The case settled on 15 February 2022 with no admission of liability. The settlement amount has been widely reported as between $12 million and $16 million, drawn from Queen Elizabeth II's private funds supplemented by Andrew's own contribution. Andrew's HRH titles and military patronages had been removed in January 2022 before the settlement was announced.

Stuxnet was a joint US-Israeli cyber-weapon — developed under the codename Operation Olympic Games — designed to sabotage Iran's uranium enrichment programme at the Natanz facility by targeting Siemens S7-315 and S7-417 programmable logic controllers (PLCs) governing IR-1 centrifuges. Discovered in the wild in June 2010 by Belarusian security firm VirusBlokAda and subsequently analysed in detail by Symantec and German researcher Ralph Langner, Stuxnet exploited four zero-day vulnerabilities. The New York Times' David Sanger confirmed the US-Israeli authorship in a 2012 report based on US official sources. Approximately 1,000 IR-1 centrifuges are estimated to have been physically destroyed by the worm. It is the first publicly known nation-state cyber-weapon designed to cause physical-world destruction.

On 24 November 2014 a group calling itself the 'Guardians of Peace' launched a wiper attack against Sony Pictures Entertainment, destroying approximately 70% of the company's corporate data. Around 100 terabytes of internal data were exfiltrated prior to the wipe, including executive emails, employee salary data, personal information, and unreleased films. The attack was linked to Sony's forthcoming comedy 'The Interview', which satirised North Korean leader Kim Jong Un. The FBI attributed the attack to North Korea on 19 December 2014. A 2018 DOJ indictment named Park Jin Hyok, a member of North Korea's Lazarus Group (Unit 180), for the Sony attack and also for WannaCry and the Bangladesh Bank heist.

On 24 January 2023, US short-seller Hindenburg Research published an 88-question report alleging that the Adani Group — the Indian conglomerate controlled by Gautam Adani — had engaged in stock manipulation, accounting fraud, and illegal parking of shares through a network of offshore entities in Mauritius, the UAE, and the Cayman Islands. The report triggered a market-cap decline exceeding $150 billion across Adani group companies. India's Securities and Exchange Board (SEBI) opened an investigation that remained ongoing through 2025. A 2023 OCCRP investigation separately linked offshore entities to Gautam Adani's brother Vinod Adani. Hindenburg itself shut down in January 2025. The verdict is partially true: the market reaction and offshore structure allegations have documented basis; the stock manipulation and accounting fraud charges were neither fully proven nor fully refuted by regulators as of mid-2026.

The CIA's covert programme to assassinate Cuban leader Fidel Castro — encompassing Operation Mongoose and related activities — is among the best-documented cases of state-sponsored political assassination planning in Cold War history. The Church Committee (1975) documented at least eight distinct plots between 1960 and 1965. Methods proposed or attempted included poisoned cigars, an exploding seashell, a contaminated diving suit, and a poison-pen device. The CIA partnered with Mafia figures including Johnny Roselli and Sam Giancana through intermediary Robert Maheu. Marita Lorenz attempted a botched poisoned-pill attack. Castro survived all attempts and died of natural causes in 2016.

Swedish Prime Minister Olof Palme was shot dead on Sveavägen in central Stockholm on 28 February 1986 as he and his wife walked home from a cinema. The case was one of the longest unsolved political murder investigations in modern history. Christer Pettersson was convicted in 1989 but the conviction was overturned by the appeals court. On 10 June 2020, Chief Prosecutor Krister Petersson formally closed the investigation, naming the late Stig Engström — known as the "Skandia man" — as the primary suspect. Engström died in 2000. Theories attributing the killing to SAPO, South African apartheid intelligence, the PKK, or other actors remain in circulation; the June 2020 closure concluded the best-supported suspect was Engström acting alone.

On 7 May 1999, during NATO's Operation Allied Force air campaign against the Federal Republic of Yugoslavia, US B-2 bombers struck the Chinese embassy in Belgrade, killing three Chinese journalists — Shao Yunhuan, Xu Xinghu, and Zhu Ying — and injuring dozens more. The Clinton administration and NATO apologised, attributing the strike to an outdated CIA map that misidentified the building as the Federal Directorate for Supply and Procurement (Yugoimport). In October 1999, The Observer published an investigation claiming the strike was deliberate, targeting the embassy because it was relaying Yugoslav military communications via its antenna. CIA Director George Tenet apologised to Congress. The incident severely damaged US-China relations and triggered protests at US diplomatic missions across China.

On 8 August 2022, the FBI executed a court-authorised search warrant at Mar-a-Lago, Trump's Palm Beach estate, seizing classified documents. Special Counsel Jack Smith indicted Trump on 37 counts under the Espionage Act and obstruction in June 2023, later expanded to 40. Judge Aileen Cannon dismissed the case in July 2024; the DOJ appealed; Smith dropped the case in November 2024 after Trump's election victory. The raid is factually documented. The contested questions concern legal propriety, selective prosecution, and the strength of the underlying case — not whether it occurred.

On 14 October 2020, the New York Post published a story based on a laptop dropped by Hunter Biden at a Delaware repair shop operated by John Paul Mac Isaac. Twitter locked the Post's account and blocked sharing of the story; Facebook reduced its reach. On 19 October 2020, 51 former intelligence officials signed a letter calling the story "classic Russian disinformation." The Washington Post and New York Times authenticated the laptop contents in March 2022. The Twitter Files (December 2022 onward) and House Judiciary Committee findings documented the suppression decision-making. The core claim — that a legitimate news story was suppressed through coordinated platform and intelligence-community action — has substantial evidentiary support.

Beginning in December 2022, Elon Musk released internal Twitter documents to journalists including Matt Taibbi, Bari Weiss, Lee Fang, and Michael Shellenberger. The releases documented FBI Foreign Influence Task Force weekly teleconferences with Twitter, DHS flagging of content for moderation, and internal deliberations around the Hunter Biden laptop story. The Supreme Court dismissed Murthy v. Missouri on standing in June 2024 without reaching First Amendment merits. The documented FBI-platform communications are real; whether they crossed constitutional lines into unlawful coercion is legally unresolved.

On 13 July 2024, Thomas Matthew Crooks fired on a Trump campaign rally in Butler, Pennsylvania, grazing Trump's ear and killing audience member Corey Comperatore. Crooks was shot dead by counter-snipers. Secret Service Director Kimberly Cheatle resigned following congressional pressure. Senate HSGAC and a bipartisan House Task Force launched investigations. The inside-job framing — that security failures were deliberate — is not supported by FBI findings or congressional conclusions, which attribute failures to coordination breakdowns and resource shortfalls.

Two peer-reviewed cluster-sample surveys published in The Lancet — Roberts et al. (2004) estimating approximately 98,000 excess deaths, and Burnham et al. (2006) estimating approximately 655,000 excess deaths — were publicly dismissed by US President Bush and UK Prime Minister Blair as not credible. Subsequent investigations raised questions about donor-disclosure transparency and pre-release political briefings. The ORB survey (2007) and the WHO/COSIT Iraq Family Health Survey (2008) produced lower but still substantial estimates. Methodological disputes among epidemiologists remain unresolved.

Air France Flight 447 disappeared over the South Atlantic on 1 June 2009, killing all 228 people on board. The BEA final report (2012) concluded that icing of Thales AA pitot tubes caused unreliable airspeed readings, triggering pilot loss of situational awareness and a sustained aerodynamic stall. Pre-crash documents indicate Airbus and Air France were aware of pitot-tube icing problems and had issued advisories without mandatory replacement orders. Lawsuits alleging corporate concealment of known defects are ongoing. The claim of deliberate industrial cover-up is partially supported by evidence of known pre-crash deficiencies; allegations of criminal concealment remain legally contested.

Air France Concorde Flight 4590 crashed near Gonesse, France, on 25 July 2000, killing all 109 people on board and four on the ground. The BEA concluded that a titanium strip shed by a Continental Airlines DC-10 on the same runway punctured a Concorde tyre, whose debris ruptured a fuel tank, causing an engine fire and loss of control on takeoff. Continental Airlines and maintenance engineer John Taylor were convicted of involuntary manslaughter in 2010; the convictions were overturned on appeal in 2012. Conspiracy claims centre on whether Concorde's known pre-existing structural vulnerabilities were concealed by Air France and Aerospatiale, and whether the Continental debris finding scapegoated a foreign carrier.

RMS Lusitania was torpedoed by U-20 on 7 May 1915 off Old Head of Kinsale, Ireland, killing 1,198 passengers and crew. The ship's manifest acknowledged rifle ammunition. A second explosion shortly after the torpedo strike has fuelled debate over whether undisclosed munitions or a boiler failure caused it. Naval historian Patrick Beesly's research suggests Admiralty signals intelligence placed U-20 in the area but no protective escort was dispatched. The claim that Winston Churchill and the Admiralty deliberately withheld protection to provoke US entry into the war is partly coherent at the level of negligence; the stronger claim of deliberate sacrifice has no documentary proof.

The battleship USS Maine sank in Havana Harbor on 15 February 1898, killing 266 sailors. The Sampson Court of Inquiry (1898) and the Vreeland Board (1911) both attributed the sinking to an external mine, fuelling the "Remember the Maine" war cry that helped launch the Spanish-American War. Admiral Hyman G. Rickover commissioned a 1976 Naval History and Heritage Command study concluding that a coal-bunker fire adjacent to a magazine was the most probable cause. Modern computational analysis (1998 National Geographic study) supported the coal-fire hypothesis. The Spanish-mine attribution is now considered the debunked framing by mainstream naval historians.

From the late 1960s through the early 1980s, the Chicago Outfit and allied Mob families skimmed unreported cash from Las Vegas casinos operated through the Argent Corporation — fronting the Stardust, Fremont, Hacienda, and Marina properties. FBI operations Strawman and Strawman II produced wire recordings and informant testimony that led to the convictions of Chicago bosses Joseph Aiuppa and Jackie Cerone and associates in 1986. The scheme is documented in FBI files, court records, and testimony. It formed the basis for Nicholas Pileggi and Martin Scorsese's Casino (1995).

Adolf Eichmann, the SS-Obersturmbannführer who administered the logistics of the Holocaust, was captured by a Mossad team led by Isser Harel in Buenos Aires on 11 May 1960. He was transported to Israel, tried publicly, convicted, and executed in 1962. CIA and BND (West German intelligence) files declassified from 2006 onward revealed that both agencies had located Eichmann in Argentina years before the Mossad operation — and chose not to act, in part to protect West German officials with wartime connections. The cover-up claim is substantially true based on the declassified record.

On 26 March 1997, 39 members of the Heaven's Gate religious movement were found dead at a rented mansion in Rancho Santa Fe, California. They had ingested phenobarbital mixed with vodka and applied plastic bags to their heads. Leader Marshall Applewhite had taught that a spacecraft trailing comet Hale-Bopp would transport their souls to a higher realm. Claims of government cover-up or institutional concealment are unsupported: the investigation was transparent, Applewhite's videotaped teachings are publicly available, and the deaths were thoroughly documented.

The Lavon Affair (also called Operation Susannah) was a failed Israeli covert operation in 1954 in which Egyptian-Jewish agents recruited by Israeli military intelligence carried out a series of bombings against British and American targets in Cairo and Alexandria. The operation was designed to be attributed to the Muslim Brotherhood or Egyptian communists, with the aim of destabilising the relationship between Egypt and the Western powers and discrediting the Nasser government. The network was exposed by Egyptian security services; Israeli defence minister Pinhas Lavon resigned over the affair in 1955. Israel officially acknowledged the operation in 2005.

Silicon Valley Bank (SVB) collapsed on 10 March 2023 in the second-largest US bank failure in history. Conspiracy claims attributed the failure to coordinated short-selling campaigns or deliberate destabilisation by financial actors. Federal Reserve, FDIC, and congressional investigations attributed the collapse to SVB's concentration of approximately $91 billion in long-duration mortgage-backed securities purchased at near-zero interest rates, which lost market value as rates rose. When SVB announced a $1.8 billion realised loss from selling securities on 9 March, a Twitter-accelerated bank run ensued. Short-seller conspiracy claims are unsupported.
