The Innocence Project estimates 1% of all inmates are wrongfully convicted: https://innocenceproject.org/how-many-innocent-people-are-in-prison/ https://innocenceproject.org/how-many-innocent-people-are-in... Others put the range between 0.027% and 4.1% https://www.nationalgeographic.com/science/article/how-many-people-are-wrongly-convicted-researchers-do-the-math https://www.nationalgeographic.com/science/article/how-many-... > So then the next terrifying question is, geeze, how many innocent people have actually been executed? > Fortunately it’s probably not many. Innocent defendants are far more likley to have their sentenced changed to life in prison than to be executed. Still, with an error rate of 4 percent, the researchers write, “it is all but certain that several of the 1,320 defendants executed since 1977 were innocent.” Of the 1,320 executions over the past 45 years, using various estimates of wrongful convictions: 0.027% = 0.35 total (~1 every 128.5 years) 1% = 13.2 total (~1 every 3.4 years) 4.1% = 54.12 total (~1 every 10 months)
