KHOU-TV (CBS) Ch. 11 Houston TX (Internet / TV) 06/02/06 It’s become the latest legal tactic to stop executions: claim the very way Texas puts people to death is “cruel and unusual.” Critics say lethal injection can leave condemned inmates paralyzed but still conscious as the chemicals kill them. Could that really happen? “Based on what I know about the Texas procedure, its extremely unlikely,” said Dr. Donald Prough, UTMB Galveston. Anesthesiologist Prough said if properly given, the amount of the chemical Texas uses to put an inmate to sleep should work within seconds. He said it could kill them in and of itself.
