Capital punishment, the death penalty, death sentence, or execution is a legal process whereby a person is put to death by the state as a punishment for a crime. Crimes that can result in a death penalty are known as capital crimes or capital offences. The term capital originates from the Latin capitalis, literally "regarding the head" (referring to execution by beheading).

Capital punishment has in the past been practised by most societies (one notable exception being Kievan Rus); currently only 58 nations actively practice it, and 97 countries have abolished it (the remainder have not used it for 10 years or allow it only in exceptional circumstances such as wartime). It is a matter of active controversy in various countries and states, and positions can vary within a single political ideology or cultural region. In the European Union member states, Article 2 of the Charter of Fundamental Rights of the European Union prohibits the use of capital punishment.

Currently Amnesty International considers most countries abolitionist. The UN General Assembly has adopted, in 2007, 2008 and 2010, non-binding resolutions calling for a global moratorium on executions, with a view to eventual abolition. Although many nations have abolished capital punishment, over 60% of the world's population live in countries where executions take place, as the People's Republic of China, India, the United States of America and Indonesia, the four most-populous countries in the world, continue to apply the death penalty (although in India, Indonesia and many US states it is only used rarely). Each of these four nations voted against the General Assembly resolutions.

George Denis Patrick Carlin (May 12, 1937 – June 22, 2008) was an American stand-up comedian, social critic, satirist, actor and writer/author, who won five Grammy Awards for his comedy albums.

Carlin was noted for his black humor as well as his thoughts on politics, the English language, psychology, religion, and various taboo subjects. Carlin and his "Seven Dirty Words" comedy routine were central to the 1978 U.S. Supreme Court case F.C.C. v. Pacifica Foundation, in which a narrow 5–4 decision by the justices affirmed the government's power to regulate indecent material on the public airwaves.

The first of his fourteen stand-up comedy specials for HBO was filmed in 1977. In 1988, the 1990s and 2000s, Carlin's routines focused on socio-cultural criticism of modern American society. He often commented on contemporary political issues in the United States and satirized the excesses of American culture. His final HBO special, It's Bad for Ya, was filmed less than four months before his death.

Troy Anthony Davis (October 9, 1968 – September 21, 2011) was an American man convicted of and executed for the August 19, 1989, murder of police officer Mark MacPhail in Savannah, Georgia. MacPhail was working as a security guard at a Burger King restaurant when he intervened to defend a man being assaulted in a nearby parking lot. During Davis's 1991 trial, seven witnesses testified they had seen Davis shoot MacPhail, and two others testified Davis had confessed the murder to them among 34 witnesses who testified for the prosecution, and six others for the defense, including Davis. Although the murder weapon was not recovered, ballistic evidence presented at trial linked bullets recovered at or near the scene to those at another shooting in which Davis was also charged. He was convicted of murder and various lesser charges, including the earlier shooting, and was sentenced to death in August 1991.

Davis maintained his innocence up to his execution. In the 20 years between his conviction and execution, Davis and his defenders secured support from the public, celebrities, and human rights groups. Amnesty International and other groups such as National Association for the Advancement of Colored People took up Davis's cause. Prominent politicians and leaders, including former President Jimmy Carter, Rev. Al Sharpton, Pope Benedict XVI, Archbishop Desmond Tutu, former U.S. Congressman from Georgia and presidential candidate Bob Barr, and former FBI Director and judge William S. Sessions called upon the courts to grant Davis a new trial or evidentiary hearing. In July 2007, September 2008, and October 2008, execution dates were scheduled, but each execution was stayed shortly before it was to take place.

Wu Ying-hua simplified Chinese: 吴英华; traditional Chinese: 吳英華; pinyin: Wú Yīnghuá) (1907–1996) was a famous Chinese teacher of Wu-style t'ai chi ch'uan. She was born in Beijing and died in Shanghai. She was the eldest daughter of Wu Chien-ch'uan, the best known teacher of Wu-style t'ai chi ch'uan. Her older brothers were Wu Kung-i and Wu Kung-tsao.

Wu Ying-hua began studying Tai Chi Chuan at age nine, and by age seventeen, she was a full-time teacher in her father's school. In 1921, she was invited to teach Tai Chi Chuan in Shanghai. In 1928, her father followed her to Shanghai and she became his teaching assistant. In 1930, she married Ma Yueh-liang who was Wu Chien-ch'uan's senior disciple. In 1935, Wu Chien-ch'uan founded the Chien-ch'uan Tai Chi Chuan Association (鑑泉太極拳社) in Shanghai. Wu Chien-ch'uan died in 1942.

After the Cultural Revolution, at about 1980, it became possible to teach Tai Chi Chuan publicly in China. About this time her brother Wu Kung-tsao was released from prison and moved to Hong Kong. Wu Ying-hua and Ma Yueh-liang, remaining in mainland China, created a simplified Wu Tai Chi Chuan Form and were again able to have public meetings of the Chien-ch'uan Tai Chi Chuan Association. They taught a large number of students in Shanghai and in their travels to New Zealand, Germany and elsewhere. Together with Ma Yueh-liang, Wu Ying-hua published several books on Wu-style t'ai chi ch'uan. The books “Wu style Tai Chi Chuan: Forms, Concepts and Applications of the Original Style,” “Wu Simplified Tai Chi Chuan,” and “Wu style Tai Chi K'uai (Fast) Chuan or Wu Style Tai Chi Fast Form” have been collected in a single volume in China. They also co-authored a Wu style sword book. Wu Ying-hua was the senior instructor of the Wu family from 1983 until she died in 1996.
