Joseph Scott Morgan and Dave Mack discuss the Manson family murders and the real injuries suffered by the victims,  as well as beheadings carried out hundreds of years ago in an effort to explain the difference in the type of injuries created by all manner of weapons that can be used to stab, slice, carve, and disembowel. Professor Morgan explains the difference between the facts of a case and how injuries and weapons are shown in film and how difficult it is to determine the source of a sharp force injury.
