I would like to move the issue to voluntary execution by the state, independent of prisoners. I support doctor assisted suicide. I simply cannot understand what the objection is, other than that some doctors refuse to do it.
OK, so my thought exercise is this:
The State of California rents out its death chamber at San Quentin to civilians who want to die. It would be a very strightforward deal, I pay for my own death, because I want to die, and no longer face my own pain. San Quentin can franchise it, if they want.
Oregon already has doctor-assisted suicide, and it is time for California to follow. However, until we do, we could at least make some money off of it.
Once a few thousand civilians take advantage of the service, there might be judges who understand that being put to sleep is not cruel and unusual punishment, and the murderers can alco be put out of existence.
