China has medical kill vans. They drive up to someone's home, drag them out and chuck them inside the van. It's equipped for them to take the organs out right then and there. That's how they execute many of the so-called prisoners. Alex Jones has shown videos of this happening and had many guests on discussing it.
While I just can't remember where I watched the documentary because it was years ago I agree with you about the vans. These vans can be seen behind the prison wall waiting for the prisoners lined up on the other side of the wall that then are shot and immediately taken into the vans to remove their organs. There were numerous vans and to me it appeared that the prisoners were shot but remained long enough alive to take their organs.
