OK, so even if we are to assume an intruder wouldn't use a stun gun to pull her from her bed for fear she would scream (and I don't know because I've never used a stun gun on a sleeping girl), why would her mom use a stun gun on her? Just to torture her?
I'm not saying she did. I don't believe the marks found on JonBenet were the result of a hit by a stun-gun at all. I would tend to believe that they were made by the scaps on her pajamas as put forth by the forensics lab.
