Obviously a horrendous tragedy, but in my opinion re-showing images such as the one in the OP of the fireball, the towers collapsing etc. just makes it worse each year. I know you can't just 'move on' over something like this, but it's better for everyone involved with it to try and put it to the back of their mind, not to try and pretend it didn't happen or that it's just 'meh' now, but to try and lessen the pain and anguish they feel every time they see images like that.
I feel the press deliberately bring those images out every year just to invoke emotions and anger from people, personally. A bit unrelated but whatever.
