Re: So a dilemma.
But in this case the expense is too great: the expense is lives, which for medicos is too great a price since they're under incredible (and usually legal) pressure to save those lives. A third option is therefore needed.
Put it this way. Balance isn't possible because BOTH ends are so heavy the beam is bending to the point of snapping. It's like the right vs. fast problem. You can't just do it right because going too slow means people DIE, and you can't just do it fast because doing it wrong means people DIE. Medicos have to get it RIGHT AND FAST at the same time. Which means you need a SIMPLE AND SECURE at the same time solution. Otherwise, people DIE and there will be cries to get something done, toot sweet. Until someone can formally PROVE this to be impossible, the argument will never end.
