I've heard that Brits coming to Switzerland (Switzerland used to be a "hotspot" for AS, but I am not sure whether that's still the case) for AS can be prosecuted. Well, apparently not the ones who ended their lives, but their relatives, on the grounds that they helped someone to kill themselves, even if all they did was by the plane ticket.
Not sure whether anyone has been indicted, but the mere idea that, say, a spouse of someone terminally ill can be prosecuted to help them fulfill their last wish is totally wrong on every conceivable level.
