The search up until 04/25/2011 was made up of teams of volunteer searchers(ground searchers)and LE/FD/CD. LE/FD/CD officials managed and coordinated the volunteer search teams. A sign in was required but there were no confidentiality agreements required to be signed by the thousands of volunteer searchers, imo.
That is unfortunate imo. In any case, I wonder how those thousands of searchers would feel if their info was released in relationship to Ms Wysocki's group?
I would not be a fan if it were me.
