think on this, if a child eats halal meats in school, and the parents are unaware, how would that sit with you, if you don't approve of the method of slaughter, it's wrong, we have been sold a bill of goods,
vote with your feet, don't buy anything that says halal - irrespective that the animal might be stunned beforehand, no one will know that.
we do have strict guidelines on animal slaughter, we know that they may not be always adhered to, only inspections at abattoirs would find that out.
