Lethal injection or time to play possum?

From CNN:

The Ohio Department of Corrections said Joseph Clark, 57, was pronounced dead at 11:26 a.m. ET following an injection of lethal chemicals at the Southern Ohio Correctional Institution in Lucasville.
Spokeswoman Andrea Dean said the execution was delayed about 90 minutes because technicians had trouble initially finding a site in Clark’s arm for the intravenous line carrying the chemicals.
Then shortly after the poisons were supposed to have been pumping into his body, she said, he sat up saying, “It’s not working. It’s not working.”

Had I been the one strapped to the gurney, I think I might have just kept my mouth shut.
