William Brydges was a Canadian man whose arrest for murder resulted in the leading Supreme Court of Canada case "R v Brydges" on the right of a detainee to access duty counsel.
 His case was a Canadian precedent, and created significant controversy after the Supreme Court of Canada upheld his acquittal.
 He was found to have been denied access to an attorney because he was not informed of legal services available to him when he told police he could not afford a lawyer.
 This case had nationwide ramifications, requiring all police officers to advise a person under arrest of the availability of legal services even if they couldn't afford them.

 At the time of his capture and arrest in March 2012, Naden was reported as being one of Australia's most wanted men and his arrest attracted international media coverage.

Thomas Horn, Jr. (November 21, 1860 – November 20, 1903) was an American Old West scout, who carried out varied roles as hired gunman, Pinkerton, range detective, cowboy, and soldier.
 Believed to have committed 17 killings as a hired gunman in the West, in 1902 Horn was convicted of the murder of 14-year-old Willie Nickell near Iron Mountain, Wyoming.
 Willie was the son of sheep rancher Kels Nickell, who had been involved in a range feud with neighbor and cattle rancher Jim Miller.
 On the day before his 43rd birthday, Horn was executed by hanging in Cheyenne, Wyoming.
Adrian P. Thomas was a father of seven children living in Troy, New York, when, in September 2008, his four-month-old son died.
 A preliminary medical examination indicated that the infant died from head trauma.
 The police interrogated Thomas for nearly 10 hours during which he confessed to throwing his son on the bed three times.
 The entire interrogation was videotaped.
 He was charged with second-degree murder, found guilty, and sentenced to 25 years to life in prison.
 In 2011, Grover Babcock and Blue Hadaegh were looking for an example of a coerced confession as the basis for a documentary film they were planning and they used Thomas' interrogation video to make the documentary "Scenes of a Crime".
 Thomas appealed his conviction based on a coercive interrogation, however, the state appellate justices of New York denied his appeal in 2012.
 Thomas then appealed his conviction to the New York Court of Appeals.
 In February 2014, the seven judges unanimously ruled that Thomas must have another trial excluding the videotaped confession.
 A second trial was held and on June 12, 2014, the jury found him not guilty of second degree murder of his infant son.
 The case created controversy about how much coercion is legally permissible in police interrogations.
Joe Lefors (February 20, 1865 – October 1, 1940) was a lawman in the closing years of the Old West.
 He is best known for the arrest of gunman Tom Horn in 1903 for the alleged murder of 14‑year-old sheepherder Willie Nickell, which has since come into question, and it has long been believed that Lefors falsified evidence helping to convict the wrong man for the murder.
