Quick: A bullet is so fast that a victim cannot have enough to even blink let alone react, rendering the death quick and near-instant.
Cheap: It would cost significantly less than the ingredients and tools for lethal injection as the main cost would be for bullets and the executioners' effort.
Guiltless: Out of the five guns given to executioners, one gun has a blank in it that is not revealed to the executioners so that they do not who actually killed the prisoner and thus wont have any shame or guilt.
Painless: Compared to the Gas Chamber, Lethal injection and electrocution; a quick bullet (or four) to the heart is so quick, and instantaneous that the vicitm will not even feel a hint of pain before dying in a flash.
Lethal Injection is very human. While gun fire is that the heart and brain functions all shut down which takes 6-10 mins. While lethal injection is at most 10 mins.
Painless: They also issue a drug called Midalozam in which induce unconsciousness while the other drugs stop your breathing and heart beat. Is it better to die by a volley shot and slowly suffer and bleeding out,Or be unconscious and let the drugs stop your heart and breathing without feeling it?
Cheap:The guns in which they give cost at least 50 dollers. That is at least under what bassamelali says either 5 guns so that will be 250 dollers.
