In the United States, capital punishment is a legal penalty throughout the country at the federal level, in 27 states, and in American Samoa. It is also a legal penalty for some military offenses. Capital punishment has been abolished in 23 states and in the federal capital, Washington, D.C. It is usually applied for only the most serious crimes, like aggravated murder. Although it is a legal penalty in 27 states, 20 states have the ability to execute death sentences, with the other seven, as well as the federal government, being subject to different types of moratoriums. The existence of capital punishment in the United States can be traced to early colonial Virginia. Along with Japan, Singapore, and Taiwan, the United States is one of four advanced democracies and the only Western nation that applies the death penalty regularly. It is one of 54 countries worldwide applying it, and was the first to develop lethal injection as a method of execution, which has since been adopted by five other countries. The Philippines has since abolished executions, and Guatemala has done so for civil offenses, leaving the United States as one of four countries to still use this method (along with China, Thailand, and Vietnam). It is common practice for the condemned to be administered sedatives prior to execution, regardless of the method used.
There were no executions in the United States between 1967 and 1977. In 1972, the Supreme Court of the United States struck down capital punishment statutes in Furman v. Georgia, reducing all pending death sentences to life imprisonment at the time. Subsequently, a majority of states enacted new death penalty statutes, and the court affirmed the legality of the practice in the 1976 case Gregg v. Georgia. Since then, more than 8,700 defendants have been sentenced to death; of these, more than 1,550 have been executed. At least 190 people who were sentenced to death since 1972 have since been exonerated, about 2.2% or one in 46. As of April 13, 2022, about 2,400 to 2,500 convicts are still on the death row.
