The US is one of the only countries in the "developed world" which still practices capital punishment AND has the highest documented incarceration rate in the world. Look at the map below for countries that practice the death penalty.
The US is the same color as some of the more totalitarian and brutal regimes.
95 have abolished it.
9 retain it for crimes committed in exceptional circumstances (such as in time of war).
35 permit its use for ordinary crimes, but have not used it for at least 10 years and are believed to have a policy or established practice of not carrying out executions or is under a moratorium
if you think the prosecutor really cares for the truth to come out, you are sadly mistaken. They just want to win a case, like a notch on your rifle barrel after a kill.
How many of you remember Illinois - where a study showed innocent people had mistakenly been put to death?
In January 2000, Governor George Ryan of Illinois imposed a moratorium on the imposition of the death penalty in Illinois. In reviewing death penalty cases since 1977, he determined that 13 death row inmates in the state had been cleared of murder charges, compared to 12 who had been put to death. Some of the 13 inmates were taken off death row after DNA evidence exonerated them; the cases of others collapsed after new trials were ordered by appellate courts. "There is a flaw in the system, without question, and it needs to be studied", Ryan said. Ironically, the Republican Governor had campaigned in support of the death penalty. Ultimately in January 2003, Governor Ryan commuted all death sentences to prison terms of life or less
