Why can't the reporters and their editors call it what it is?
Beheading with a knife while having your neck sawed until you are dead and disfigured = cruel murder = execution
Videotaped and televised beheading = snuff film.
I think I saw some comment in Newsweek about these being Jihadi snuff films. Yep, they are.
But, the term is being used in too sanitized a way. Why not just call it head removal with adverse consequences?
Beheaded = terminated = passed on = died.
