TWFirst: I think the families wanted to go down there at least once as kind of an informal funeral, since chances are their loved one's remains won't be found (even though they found 2 police officers yesterday). But I don't see them arguing to go down there every day. I see it this way:
3,000 innocent people were murdered here
3,000 innocent people including my husband, wife, child, friend, colleague, neighbor, etc. were murdered here.
Neither are easy to deal with. But those with a personal connection to someone who was killed may find it tougher to deal with a "birds eye" view of the murder site.

I guess it's easier for them to stare because it doesn't affect them
