Why doesn't Elijah Wood simply make his "reading and research" on child abuse in Hollywood public, if he believes abuse is an ongoing concern? [Details]?

By linking the assertion to Jimmy Savile, sexual abuse is implied, and it seems to me that systematic child abuse in Hollywood is a serious charge to make without knowing specifics.

If someone not involved in the sexual abuse had specifics, how could they rationalize not revealing that information?
