(From the N.Y. Times) Saying he was now “paroled to my Father in heaven,” a convicted killer in Ohio on Tuesday became the first person in the United States to be executed with a one-drug intravenous lethal injection.

While praising the shift to a single drug, death penalty opponents argue that Ohio’s new method, and specifically its backup plan of using intramuscular injection if the authorities are unable to find a usable vein, has not been properly vetted by legal and medical experts. Since it had never been tried on humans before, they contend it is the equivalent of human experimentation.
