I initially read the topic as "goes on shopping spree", so was disappointed as to its contents. Not so much the subject itself, tragic as these things invariably are, but disappointed by the name-calling, swiping, accusations, biting and general rule-breaking that's gone on in this thread.
Why is it so often a 'disgruntled ex-employee' who ends up going on a rampage?
Because gruntled people generally go on with their lives without hurting each other.
As I think we all should, while I consider whether warnings need to be issued for some of the comments in this thread.
