I went down to ground zero about a month after. On the way back from college. I had taken the Amtrak from Hartford to Grand central and figured I should go down and just pay some respect. I had known some people from my town who passed away. Awful. It still smelled like smoke and debris. And there were barriers up and thousands of pictures of “missing” people who were obviously gone. I saw an Asian group of people taking pictures and I was fuming until I saw a cop standing there. He saw me staring at them and he looked at them all for a moment as well. Then he looked back at me and leaned over and said “They don’t know. Some people don’t know.” And it made me realize that some people want to take that picture because they know something is important even if it’s fucking disgusting. So when people go to ground zero and the reflecting pools and the museum and have pictures I try not to take offense to it. They don’t know.
People just don't know, especially tourists, or people who were too young or not even born when it all happpenned.
I went with my wife after like 15 years (we live 40 miles away)to see the pools and it was getting on my nerves seeing people taking selfies and smiling..etc, as if they weren't standing literally on a spot where nearly 3,000 were essentially murdered.
But i realized that most don't know or are/were too far removed from it, due to distance, time, or both. People go to Gettysburg, Normandy, Pearl Harbor, Auschewitz...etc or places in other countries where horrible acts have happened and to most (even us) it's just a place that they read about in a book.
People are always going to be people.
