Quoting John Keown <jdk(_at_)nni(_dot_)com>:
So if my employer does not have an explicit policy against guns at work just
a metal detector at the entrance it is OK to bring a gun into the office.
Yes. Perhaps they just wish to write down who brought one, to know who can
defend the building if attacked.
Why not go a little further and say since my employer does not have an
explicit policy against killing a fellow employee I can just shoot them.
Because laws apply too.
It is obvious that your employer (Digital Equipment Corporation) does not
want personal email being sent from your employment.
There hasn't been a "Digital Equipment Corporation" in about a decade, and I
never worked for them. Try again.
