I not only support medically assisted suicide, but it should not be the business of the government to get involved.
If you have a terminal illness, or are in chronic umanagleable pain you should be allowed to ask your doctor for the only release available. They should not be given, however, without your primary MD's authorization, a secondary reviewing MD (someone who has not been involved in your healthcare), with a short period of review by the applicable State's Medical Review Board.
This is one of the things that really disappoints me with the Bush administation, heck, they never even offered any apologies when the autopsy for Terri Shiavo was released, even though the weight of her brain was far below the normal even when compared to someone who had been in a persistive vegatative state.
