Is this unusual family ignorance?

[Questioner]

Just a few months ago I discovered the TV series "The Locator." (http://www.wetv.com/the-locator/) It's a documentary series about an investigator, Troy Dunn, who has a team that tracks down long-lost people. It's a business but the series shows the charity cases they take, typically involving adoption. It's fascinating to see how much family means to some people, and how indifferent some others are to relatives, reunions, and reconciliations. In my opinion, Troy Dunn is a very wise and compassionate person. The show has really helped me to even be able to put these questions into words.

Ahktu, what do you think about open adoption laws that would require adult children to be provided their complete adoption records on request? Do you think that's a good idea? Do you see any drawbacks?
