Missouri Gov. Jay Nixon is urging renewal of exemptions from Missouri’s open records law for security systems of government buildings and policies for responding to terrorism, according to an article from The Associated Press.

The exemptions protecting this information from disclosure expired at the end of 2012, the article says. Nixon has scheduled news conferences on the topic Friday from the University of Missouri-St. Louis (UMSL) and the Missouri State Highway Patrol General Headquarters in Jefferson City. Law enforcement and public school district officials were scheduled to take part, AP reports.

One exemption covered operational guidelines and policies developed by law enforcement, public safety agencies and others for preventing and responding to terrorist incidents. The other exemption dealt with security systems and structural plans of property owned or leased by government agencies, according to AP.
