extensive process that is carried out by the fatal mixture of three drugs. The person is restrained in a gurney and on signal from the warden a dose of sodium thiopental is given to them to cause unconsciousness. The next step is to inject pancuronium bromide‚ a muscle relaxer‚ which will disable the lungs and diaphragm. Last‚ fatal cardiac arrest is induced by potassium chloride being injected (“Methods of Execution”). This process may sound like a full proof procedure; however‚ there are still many kinks
