I dont have any problem with a new investigation, but my issue is that when any one theory is debunked in five seconds flat, the 911 CT'ers either go to something else or just say its a secret and that is why they cant prove or explain their claims.
I am game for anything, but so far - 10 years later, not one 911 ct'er has yet to put forward one coherent CT that cant be debunked in 5 seconds flat.
