Fundamentalist extremists say the the craziest things.
At a recent debate over the battle for Islamic ideals in England, a British-born Muslim stood before the crowd and said Prophet Mohammed's message to nonbelievers is: "I come to slaughter all of you."
"We are the Muslims," said Omar Brooks, an extremist also known as Abu Izzadeen. "We drink the blood of the enemy..."
I'm not an expert on Muslim dietary law, but I'm sure human blood is not halal.
