I'm sitting here listening to the news,  and some wacko just went nuts
(with guns) in a factory in Mississippi.  Why the heck is it,  when the
news media refers to an incident of this type,  that they always refer to
the perp as "a gunman"?

If he'd used a knife,  would they call him "a knifeman"?  How
about other implements...?
