The thing to remember is that the final verses of Leviticus 17 are pretty clear what the penalty of eating this sort of flesh was.
And every person who eats what dies of itself or what is torn by beasts, whether he is a native or a sojourner, shall wash his clothes and bathe himself in water and be unclean until the evening; then he shall be clean. 16 But if he does not wash them or bathe his flesh, he shall bear his iniquity.”
Basically take a shower and be unclean for the evening. So although the command to not eat blood is clear in my mind the fact that someone taking it is considered to have disassociated himself or is disfellowshipped goes grossly outside the bounds of the scriptures.
Interesting that these final verses are rarely if ever read or quoted by the Watchtower.
See they can't back off of it now. Too many have been killed. They're stuck with the hard and fast blind prohibition that completely ignores the sanctity of life in a trauma situation.
