There is no doubt that this is probably the greatest and most horrible crime ever committed in the whole history of the world, and it has been done by scientific machinery by nominally civilised men in the name of a great State and one of the leading races of Europe. It is quite clear that all concerned in this crime who may fall into our hands, including the people who only obeyed orders by carrying out the butcheries, should be put to death after their association with the murders has been proved.
