??? When was it ever stated on screen that the original is destroyed?
Nowhere. Not a single onscreen moment ever said that. And as I keep saying, TNG proved the opposite.
Not to mention that if it did work that way, no one in their right mind would use it.


Does anybody think anyone will be that stupid to run a company to the ground by killing people using transporter? So, I guess they are safe and reliable! I'm not afraid of it anymore! 

On second thought! I'll take a shuttle! No one is going to make me! Do I sound like Dr. Macoy? 
Do I have to keep repeating myself? Just go watch "Realm of Fear". It conclusively proves it would actually be you.
