1. There is no required public viewing of these executions
2. These executions are carried out in way too "humane" of a manner.
Some 15 year old thinking about putting a bullet into someone isn't going to be detered by the very slim chance that he heard about a fellow gang member being executed by lethal injection two weeks earlier. HOWEVER, the memory of being forced to watch that fellow gang member do the "rope dance" might just be enough to make him think twice.
