Jehovah's Witnesses are a Christian cult with 7.6 million followers worldwide.
The cult is most well known for its door-to-door ministry, refusal to fight in war, and refusal to accept blood transfusions.
Jehovah's Witnesses believe that blood is the personal property of God, and that God commands blood be poured on the ground. JW's are permitted to eat meat and are directed to follow their own conscience when using blood components, however whole blood, white blood cells, and red blood cells are strictly forbidden.
JW's have gone so far as to deny children life-saving treatment to maintain this restriction. This policy has resulted in numerous children being separated from their JW parents for abuse. JWs have been known to kidnap these children in order to allow them to die, rather than accept life-saving treatment.
