Rishi Prakash Tyagi was a former Assistant Commissioner in Delhi Police. He was reported to be the first senior police officer in India to be given the death sentence for the custodial death of a person, although the punishment was later reduced after an appeal in a higher court. [1] [2]
In August 1987, when Tyagi was the station house officer (SHO) of Vivek Vihar police station in East Delhi, Mohinder Kumar and Ram Kumar were arrested on charges of eve teasing and subsequent assault on a police constable who had gone to arrest them. Both were reportedly tortured and a day later were found dumped in nearby fields. While Mohinder died in hospital, Ram Kumar survived and was a crucial witness during the trial. [2]
The trial court, while sentencing Tyagi on 18 December 2006, said the charges of murder were proved and it was one of the 'rarest of rare cases' that merited death penalty. [1]
The sentence was appealed in the Delhi High Court and in March 2008 Tyagi was convicted only for culpable homicide, as the intention to murder was not proved and his death sentence was commuted to eight years of 'rigorous imprisonment' with a fine of two lakhs rupees. [2]

The 2012 Delhi gang rape and murder, commonly known as the Nirbhaya case, involved a rape and fatal assault that occurred on 16 December 2012 in Munirka, a neighbourhood in South Delhi. The incident took place when Jyoti Singh, a 22-year-old physiotherapy intern, was beaten, gang-raped, and tortured in a private bus in which she was travelling with her male friend, Avnindra Pratap Pandey. There were six others in the bus, including the driver, all of whom raped the woman and beat her friend. She was rushed to Safdarjung Hospital in Delhi for treatment and transferred to Singapore eleven days after the assault, where she succumbed to her injuries two days later. The incident generated widespread national and international coverage and was widely condemned, both in India and abroad. Subsequently, public protests against the state and central governments for failing to provide adequate security for women took place in New Delhi, where thousands of protesters clashed with security forces. Similar protests took place in major cities throughout the country. Since Indian law does not allow the press to publish a rape victim's name, the victim was widely known as Nirbhaya, meaning "fearless", and her struggle and death became a symbol of women's resistance to rape around the world.

On the night of September 6, 2018, 26-year-old accountant Botham Jean was murdered in Dallas, Texas, by off-duty Dallas Police Department patrol officer Amber Guyger, who entered Jean's apartment and fatally shot him. Guyger, who said that she had entered Jean's apartment believing it was her own and believed Jean to be a burglar, was initially charged with manslaughter. The absence of a murder charge led to protests and accusations of racial bias because Jean—an unarmed black man—was killed in his own home by a white off-duty officer who had apparently disregarded police protocols. On November 30, 2018, Guyger was indicted on a charge of murder. On October 1, 2019, she was found guilty of murder, and was sentenced to ten years' imprisonment the following day. The ruling was upheld on appeal in 2021.
