For example, the names, addresses and positions of municipal employees are available for disclosure but medical information relating to these employees would not be. Another group of exceptions applies to certain internal operating documents of governmental entities. These exceptions would, for example, protect an instructional manual on computer security from public disclosure. These exceptions are based on the realization that there should be a free flow of advice and opinions between policy makers as policy is developed, without fear that the comments would become public. Note, however, that factual materials upon which policy positions are or have been based are not exempt.
Investigatory materials compiled by law enforcement officials are another important exception.
These materials may be withheld if effective law enforcement would be prejudiced by disclosure. There is also no obligation to disclose the identity of persons who apply for a firearms license or documents in connection with the sale or transfer of firearms or ammunition. A request for public records should be made to the custodian of the records and may be made orally or in writing. Responses to the request should be made without unreasonable delay but definitely within 10 days. If the request is denied the custodian must give the specific legal basis for withholding the materials.
