"Does anyone have a link to a more authoritative source than Hannity? It could very well be true, but I'd like to see some sourcing on this number."
It is Ollie North who is putting forth the info, not Hannity.
somewhere in my library I have an apaprently scholarly book on the post V-E day "werewolves" or nazi resistance. mY memory is that it has a lot of interesting detailed plans by them, but it certainly didn't discuss causing deaths above a few dozen. I'll see if I can dig it out.
