This method was active during the Nazis era. They loaded up people into vans that were modulated in to mobile gas chambers.
The Chinese government sees this as an easy, cheap and yet "respectable" way to commit these execution We have not sold our execution cars to foreign countries yet
, says a Chinese spokesman. When all put into perspective, when it comes to the Chinese, this IS a respectful way to die: until 1905, the Chinese used a method of execution called "death by a thousand cuts"- the prisoner's eyes were removed in order to prevent him from knowing which part of his body is being cut off, then his ears, lips, nose, fingers etc were removed before cutting off whole limbs.
The question of human rights comes to mind instantly in this case, yet it gets seriously creepy when you learn that the prisoners aren’t just killed in these vans, but their internal organs are being removed for additional use (transplants and research).
I think that there's a place to hold an investigation by the ICJ (international court of justice) in order to stop this violation of human right. As a global modern society- we should not let this continue.
