Doesn't theft with a gun have a name?

>> "Whether committed with a gun or a keyboard - theft is theft," said U.S. Attorney Chuck Rosenberg, who led the prosecution against Griffiths.

As many others have pointed out, Griffiths was guilty of copyright infringment (and probably aiding others too, I suppose) - perhaps theft with a keyboard. However, theft with a gun is something entirely different, it's armed robbery - an entirely different crime.

I can't recall the last time a copyright infringement went wrong and someone was killed (though I am sure someone with better google skills will find it).
