If your firewall is not working, it should not be passing packets.

Yes; your arguments all seem to depend on that property being true.

But we call it a *failure* for a reason, Owen.  

What the probability is of a firewall failing in such a fashion as to *stop
filtering, but still pass packets* depends -- as you have pointed out -- 
entirely on its design.

As *I* have pointed out, not all firewalls are created equal, and there are
a helluva a lot of them out there for which this desirable property *simply
is not true*.

Sticking your head in the sand on this point is not especially productive.
