You woke up tomorrow and the date was 01/09/2001....you know what is about to happen but no-one else would...
Now
would you even bother try and warn the world? If you did, would anyone listen to you?
.....Lets see, If I warned a group of people that NYC was to be attacked and they don't listen to me...but then it does happen, what would happen to
me? a bit suspisious isn't it....
