Then there's the rather creative method of theft intended to avoid
detection
which was employed recently (for obvious reasons I will not go into
details). Suffice to say the use of that method on the wrong cables could
result in a decidely non fail-safe situation.

Doesn't the absence of a signal indication where expected indicate "Stop" or
the most restricting indication possible?

That alone is fail safe.
