One has to be either directly involved in the crime (if he is not already executed) or an idiot to not see the obvious, but fortunately there are many sane, knowledgable people who talk with logic, and there were three thoudand innocent people murdered on that day and millions more as consequence.
Asking difficult questions does not change the facts, but not asking protects the criminals.
One day, truth will come out, and I hope it does in the life time of "debunking squad".
