Quite right.
But in the final analysis some human must be given the power to make that decision, and in our society, for better or worse, we have this whole bit about due process.
Some doctor's hunch or opinion is at best problematic as a way of deciding who gets locked up for years.
I don’t think we disagree much.
I always like to take a situation like this and drive a stake in both ends, then get people to speculate on where the line in the middle goes.
We have all seen people that there is 100% no doubt they should be institutionalized.
And then we can all look at people and say 100% they shouldn’t.
All the contention comes around with that gray area, and where you divide the issue into one or the other.
