Legitimate Policy Reasons Against Full Disclosure

I believe the State may have a legitimate interest in placing some limits on the non-privileged discovery it produces.  Under the court rules, a party seeking discovery can obtain information that goes beyond what is relevant to the issues in the case to include additional information that is reasonably calculated to lead to the discovery of relevant evidence.  The State may have a legitimate reason to prevent production of material that is of at most attenuated relevance, but would cause confusion or harm if produced.  For that reason, I was hoping to begin a dialogue with the Attorney General to find some middle ground between 100% publication of all discovery materials, and 0% publication, as the Attorney General has chosen to do.
