It was certainly a powerful day and has changed the world, since this time all we hear about now is terror and ISIS or whatever they change the name to, slowly but surely our privacy and individuality is being eroded to the point that in another 10 years or less we will be living in a Minority Report / Big Brother planet.
My heart goes out to all those that lost family and close ones to this incident, it is one of those times that you will remember exactly where you were and what you were doing when it happened.
