I DID read your whole post and it did not make any sense to me. I interpret "scrubbing" as "editing out".<quoted text>
You could have saved yourself a lot of typing if you read my whole post. The show is set in the '80's. The current WTC didn't exist. The twin towers did.
And I think the worry about a survivor's child is irrelevant. Millions of people have been killed in numerous horrible ways that are shown on TV and in movies every day. What happened at the Twin Towers was horrific, but you do it a disservice, I believe, if you scrub/ignore it.
You said: "it is set in NYC in the '80's, and they are scrubbing the footage of the Twin Towers"
If it is being filmed today, then there is no footage of the twin towers to scrub/edit out. What exactly do you think I did not read?
