Some Muslims are willing to stun electrically, not all of them. I grant that electrical stunning is a modern notion, and therefore not essential, but I disagree re removing the blood. In the UK, I used to buy raw wild hares, all vacuum-packed, with at least 1 litre of raw blood in them, not counting the vast amounts of blood already present in the raw meat.
Anyway, Tony Robbins, an almost-vegan, used to say that the primary taste of meat was due to the blood in it.
