Answer 1

In todays liability climate, perhaps this quote will
explain:
"In the pursuit of Design for Public Safety, the best
you can do is to guard against someone doing the
stupidest thing you can imagine.
Satisfied that you have done this to the best of
your ability, you must simply, fearfully, await the
inevitable appearance of the fool
who does something more stupid than you could
have ever imagined."
