> For many years, it has been known that China uses execution vans, kind of like specially outfitted ambulances, to more efficiently carry out its exceedingly large number of executions. The method of killing in these vans is lethal injection, which has been slowly but surely replacing the firing squad as China’s preferred means of execution, and both lethal injection and the vans are believed to facilitate the widespread practice of harvesting organs of the executed prisoners, an unbelievably appalling practice.
