"She reported seeing the bulldozers on the site - the help with digging the graves is a known fact" - Jim Carroll

Now I asked a pal of mine who operates heavy plant machinery about this and his answer prompts me to ask you yet another question that you will no doubt ignore Jim:

Explain to us all how you would use a bulldozer to excavate a mass grave?

His take on the problem was as follows:

The area you would require would be massive.

You could only do it by "scuffing" the earth and that would take an eternity to transition into and out of the hole until you reach your target depth.

You would have to keep stopping and starting to clear and reposition the spoil heap. You would have to reposition all the spoil to fill in any hole.

That he said would be difficult enough in open fields - in a built up area in the centre of a city? Impossible.

That Jim is why when carrying out earthworks professional construction engineers use "Excavators" for digging holes NOT bulldozers - for a mass grave Jim you do need a hole don't you?
