So is it agreed Sammie did the shooting

 that we never see or hear about the gun again, and was merely a ploy used to question forever if Sami, by throwing the gun in the river, actually did the shooting, or can now also argue the fact that it also had E.J.’s fingerprints on it, indicating that he may have shot himself.  The videotaped confession can always be found at some point and destroyed, perhaps by Nicole, or perhaps Will or Chad ….. and then what???  I don’t believe that the gun will ever be found, and I don’t think for a minute that E.J. has it.
