PROTON TORPEDOES CAN'T MELT SPACE STATIONS. Particularly ones the size of a small moon.
You can clearly see from the footage that the station was destroyed from the inside. CONTROLLED DEMOLITION.
Oh, and we're supposed to believe the official story that some magic proton torpedoes made it all the way from a tiny exhaust port to the reactor core? Have you seen the size of the exhaust ports on a Freedom Station? They're no bigger than a womp rat. Impossible to bulls-eye. Or are we to believe some magic force guided them in? Tell me another one.
WAKE UP DROIDS!
