I didn't really get that out of it at all, but I developed a skill to see past a lot of the garbage. It was fear-mongering and overall just a scary way of saying China has reduced the use of death penalty, there are better mechanisms in place to prevent unlawful/unnecessary use of death penalty, and a drive to replace gunshot execution with lethal injection. The "victims" included are simply multi-million dollar fraud (essentially) and an abused kid that went on to (cw: violence) rape and kill.

You are right, in that there seems to be no widespread use of this van in the event that it is seriously used.
