注射刑作为美国司法实践中先行树立起来的一种新型行刑方式，在其执行过程中并非波澜不惊的顺风顺水。然而，在其路途探测过程中，面临不断质疑的嘈杂之声，并没有彻底颠覆注射刑不断修改更正的进取决心，恰恰相反，这些现实问题倒是更好促成了其完善实体内容与程序设计的良好宏愿，尽管这一方案设计还处于摸索试错阶段。其实，就现实困难来说，“注射刑能够走多远”的提问是支持者与反对者都没有信心保证的事情，但是支持者们谦虚接受反对者提出的切中要害的责难、推进注射刑改革的努力至少给我们呈现了一个未来图景：只要与社会进化的时代价值相契合，注射刑将“能够走多远就要努力走多远”。

The Code now states in pertinent part：All persons who have been convicted of a capital offense and have had imposed upon them a sentence of death shall suffer such punishment by lethal Injection. Lethal Injection is the continuous intravenous Injection of a substance or substances sufficient to cause death into the body of the person sentenced to death until such person is dead. See Laura C.
