Well, their “history” section says
“It was the New York/New Jersey Port Authority, through the We Will Never Forget™ association with D.A.R.E., that made possible the acquiring of a portion of the World Trade Center’s remaining standing steel structure. This portion of metal was processed and used to insure that plaques would have the symbolic amount of metal from the remaining structure.”
I think it’s a fancy way of saying they bought some of the scrap metal, probably without saying what they were going to do with it…not that fancy, though, as “acquiring” would be better off as “acquisition”. D.A.R.E. has disassociated themselves, though…
