Recently a Muslim prisoner convicted of sexual assault used anti-discrimination laws in order to demand halal(sp?) food.
If a person commits a crime and is sent to prison as punishment, I don't believe they should get to dictate how their lives are run. I believe they forfeit all those rights once they make the decision to commit a crime. I also believe that if it's for religious reasons that they require the food (or any other special priviledges) then perhaps they should have thought of that prior to committing the crime. I'm not sure there's any religion which stipulates in their doctrine that it's ok to commit sexual assault. Most of them would say they're going to hell anyway, so what does it matter? Unless you're catholic of course. Then all you have to do is say a few hail mary's and you'll be fine.
