Bridge jumpers are self selected group of mostly physically healthy people suffering from the mostly temporary/treatable mental health issue of depression. I think almost nobody would argue that depression should qualify you for assisted suicide. Also, jumping off a bridge is probably the most terrifying method of suicide available. It's practically suicide-by-torture, yup, you're gonna regret that. It's a very, very different scenario than people who are in unrelenting agony and almost certain to die in X weeks/months, saying goodby to their families, going to sleep, and not waking up again. Do you think if you gave them a placebo, let them wake up again and asked "are you _really_ sure about this?" that many of them would change their minds? Probably never been done, but my guess is you'd get very few changed minds.
