Who gives two sh*ts about "proof" regardless of what the government did or did not do that day, thousands of inncoent lives were lost unless you're one of those fools who deny even that fact...
I understand you want people to "think" as you put it. But think about this, if you lost a loved one or a friend in a senseless tragedy...would you want people to debate whether or not the event was "an inside job?" Would you want that wound ripped open over and over again by misguided people spouting nonsense they cannot prove? Would you want that event and the memory of your loss to be bandied about as a talking point for a senseless conspiracy?
There is nothing "new" to be brought into this "topic" as you call it. Unless anyone here has a time machine or can talk to the dead. All this thread does is treat the mass murder of thousands of innocent people as a conspiracy! Which is no only unproveable by anyone here, but completely disrespectful to the memories of those heroes and victims.
