an execution goes wrong in some other way. there's also the matter of how the execution chamber is set up. i can't get this out of my head. "tulsa world" found the drugs are administered from a room that is walled off from the actual person into whom the drugs are being pushed. they describe it as a cramped dimly lit room next to the death chamber where three volunteer executioners push syringes of lethal drugs into the veins of an inmate they cannot see. the iv line runs through a hole in the wall. the room is dim enough they have to use a flashlight to see in the room. they cannot see who they are drugging at all. if they need problems or have to communicate with the warden or staff in the next room along with the prisoner they are killing through the wall, to communicate with them, "the executioners stick colored pencils through holes in the wall where two iv lines feed into the inmate's body. if you saw red, there might be possible problems" said a deputy warden. but if you stuck the yellow pencil or the black pencil through the wall, then everything's okay. that's the system. and then there's the issue of autopsies.
