As former Perry Mason fan...
Did I do or say something that displeased you? If not, why did you stop loving me?
You don't need all the facts and circumstances to understand the fundamental question Of course, we need them to find an answer.
Suicide and attempted suicide were, at one time, criminal offenses but no longer are. The police, etc., interfered with what the man was doing without any excuse or justification, in law.
The man was doing something perfectly legal -- that is he was trying to kill himself.
That was his choice to make, whatever we may think and whether or not we agree. I am sure his pain and suffering must be immense!
Suppose a woman chooses to medically abort her badly deformed fetus. Leaving all side issues on the side for the time being... does the child who is born severely handicapped then have a claim against those who refused to abort her/him? Her/his suffering and expenses must also be immense. What about the mother?
These are cases about what we might call "wrongful life"! Chew on that concept!
What these types of cases make obvious is some of the convoluted ways we think about the law!

p.s.. "Volenti non fit" does not fit! That principle is about a person who chooses to get involved in something or some situation which puts her/him at risk and then complains s/he got more than what s/he might reasonably have expected... not a perfectly accurate description of the concept, but that is the point!
