I would have to agree.  In IT and some software development I also see
it lacking, but in security it is essential.  I hardly ever do any kind
of analysis without also looking at packet dumps, otherwise it's
diffucult to really get a feeling for the behaviour of the network (in
my opinion).

When I first started wearing my trusty SYN/ACK shirt around I was
horrified when I received so many questions from my collegues.
