The Ford Heights Four (Verneal Jimerson, Dennis Williams, Kenneth Adams and Willie Rainge) were formerly imprisoned convicts, who were falsely accused and convicted of the double murder of Lawrence Lionberg and Carol Schmal in Ford Heights, Illinois and later exonerated.
 Jimerson and Williams were sentenced to death, Adams to 75 years in jail and Rainge to life.
 Following the murder in 1978, the four spent almost two decades in prison before being released in 1996.
 This miscarriage of justice was due to false forensic testimony, coercion of a prosecution witness, perjury by another witness who had an incentive to lie, and prosecution and police misconduct.
 The DNA evidence uncovered in the investigation to clear their names eventually lead to the arrest and conviction of the real killers.
In the early hours of March 13, 1964, 28-year-old American bar manager Kitty Genovese was stabbed to death outside her apartment building in Kew Gardens, a neighborhood in the New York City borough of Queens.
 28-year-old Manhattan native Winston Moseley was arrested during a house burglary six days later and, while in custody, confessed to killing her.
 At his trial, he was found guilty of murder and sentenced to death; this sentence was later reduced to life imprisonment.
 Moseley died in prison on March 28, 2016, at the age of 81, having served 52 years.
The Jencks Act,  /3500 § 3500  , provides that the government (prosecutor) is required to produce a verbatim statement or report made by a government witness or prospective government witness (other than the defendant), but only after the witness has testified.
 Jencks material is evidence that is used in the course of a federal criminal prosecution in the United States.
 It usually consists of documents relied upon by government witnesses who testify at trial.
 The material is described as "inculpatory", favoring the United States government’s prosecution of a criminal defendant.
 The Jencks Act also covers other documents related to the testimony, or relied upon by government witnesses at trial.
 Typically, the material may consist of police notes, memoranda, reports, summaries, letters, related to an indictment or verbatim transcripts used by government agents or employees to testify at trial.
 This also includes a witness's grand jury testimony, if the witness testified at trial.
The Witness is a 2015 American documentary by director James D. Solomon as his directorial debut.
 The film was Produced by Solomon, Executive Produced by William Genovese and Co-Produced by Melissa Jacobson.
 It is narrated by Genovese which investigates the killing of his sister, Catherine Susan "Kitty" Genovese, in Kew Gardens, a neighborhood in the New York City borough of Queens, on March 13, 1964, by Winston Moseley.
The Capital Punishment Amendment Act 1868 (31 & 32 Vict.
 c.24) received Royal Assent on 29 May 1868, putting an end to public executions for murder in the United Kingdom.
 The Act required that all prisoners sentenced to death for murder be executed within the walls of the prison in which they were being held, and that their bodies be buried in the prison grounds.
 The Act was prompted at least in part by the efforts of reformers such as Sir Robert Peel and Charles Dickens, who called in the national press for an end to the "grotesque spectacle" of public executions.
 Abolition of public executions was one of the recommendations of the Royal Commission on Capital Punishment 1864-1866.
 A similar measure, the "Capital Punishment within Prisons Bill", had been introduced in 1867 but failed for lack of parliamentary time.
Capital punishment (""doodstraf"" in Dutch) in the Netherlands was first abolished in 1870, though only in criminal law, by the Dutch justice minister .
 Following the abolition of the death penalty, life imprisonment was made an official punishment in 1878.
John Albaugh is the former Chief of Staff to Congressman Ernest Istook and was a cooperating witness in the Department of Justice investigation of Kevin Ring, a lobbyist and an associate of Jack Abramoff.
 In June 2008 Albaugh pleaded guilty to conspiracy with Kevin Ring.
 As part of his plea agreement Albaugh wore a wire during a conversation with former Congressman Istook, testified for three days during trial, and provided other assistance to the government.
 However, Albaugh’s plea agreement fell apart when he informed the government that his actions were motivated by campaign contributions provided by Kevin Ring to Congressman Istook, and not by tickets to sporting events or meals provided by Ring to Albaugh.
 As a result of breaking his plea agreement the government requested Judge Ellen Segal Huvelle to sentence Albaugh to 27 months in prison.
 Judge Huvelle, however, rejected that request and instead sentenced Albaugh to four months in a half-way house citing his cooperation with the government investigation and saying “There are three or four Congressman out there that will never see the light of day for their actions, and we’re blaming the staffers,”.
 Huvelle declined to fine Albaugh or require him to perform community service because of his work with a non-profit organization which operates schools and medical clinics in Afghanistan saying that it was unnecessary.
Susan Newell (1893 – 10 October 1923) was the last woman to be hanged as capital punishment in Scotland.
 She was arrested after acting suspiciously and the discovery of the body of a thirteen year old newspaper boy, John Johnston.
 Although there were no witness accounts of him being killed, circumstantial evidence was presented at her trial.
 She was found guilty of his murder, a plea of insanity was rejected and she was sentenced to death.
In the British Armed Services, jankers or Restrictions of Privileges is an official punishment for a minor breach of discipline, as opposed to the more severe punishment of "detention" which would be given for a man committing a more serious or criminal offence.
 To be "on jankers" meant the serviceman or woman had been put on a charge by a non-commissioned officer (NCO) or occasionally a commissioned officer, (referred to in service slang as "being put on a fizzer") and so having his alleged offence entered on a Charge Report (Army or RAF Form No. 252).
 After appearing before an officer, the punishment might be ordered by the officer only after he has heard the evidence and had considered any mitigating factors.
Leslie Louise Van Houten (born August 23, 1949) is an American murderer serving a life sentence in relation to the 1969 killings of Leno and Rosemary LaBianca, when Van Houten was 19 years old.
 She was arrested weeks later, and convicted at the main Charles Manson trial in 1971, at which she repeatedly sabotaged her own defense, and tried to exculpate Manson.
 She was convicted and became the youngest woman ever sentenced to death in California.
 However, executions were halted in the state in 1972 after the California Supreme Court ruled that the death penalty was unconstitutional in "The People of the State of California v. Robert Page Anderson", 493 P.2d 880, 6 Cal.
 3d 628 (Cal.
 1972).
 She was granted a new trial at which her defense to the charge of first degree murder was diminished responsibility, but the jury could not agree on a verdict.
 At a third trial, she was convicted and sentenced to life in prison, although with a possibility of parole.
 In relation to her case, high courts, parole boards, and the state governor have said that an inexplicable or racial motive for murder could merit exemplary punishment and outweigh any evidence of subsequent reform.
