that's not accurate - the line continued for over an hour and near everybody in attendance at the funeral proceeded past the casket after Nancy's departure. It was so late & long, in fact, I wondered if they breached the sunset provision. Later in line it even appeared as those who'd played in the band came by, two by two, and, near the end, I also saw Chris Wallace (FNC) stop, move along and then wait for his dad (Mike Wallace / CBS 60 Minutes) who'd stop to follow.
The other folks in attendance did file past the casket and stop in front of it, but no one, other than family members it seems, actually went up on the platform where the casket was placed.
