注射死刑
Lethal injection was proposed on January 17, 1888, by Julius Mount Bleyer, a New York doctor who praised it as being cheaper than hanging. Bleyer's idea was never used, due to a series of botched executions and the eventual rise of public disapproval in electrocutions. Lethal injections were first used by Nazi Germany to execute prisoners during World War II. Nazi Germany developed the Action T4 euthanasia program as one method to dispose of "Lebensunwertes Leben" ("life unworthy of life"). The British Royal Commission on Capital Punishment (1949–53) also considered lethal injection, but eventually ruled it out after pressure from the British Medical Association (BMA).
