As previously stated, the information you have requested is exempt from disclosure by MGL c. 4 s. Disclosure of the information contained in these documents would not be in the public interest and would prejudice the possibility of effective law enforcement. The protection of such investigatory materials and reports is essential to ensure that the Department can continue to effectively monitor and control criminal activity and thus protect the safety of private citizens. More speci?cally, disclosing the existence of and capabilities provided by the type of equipmentftechnology referenced in your request would reveal sensitive technological capabilities possessed by the Department, and other members of the law enforcement community, and may allow individuals who are the subject of investigation wherein this equipmentx'technology is used to employ countermeasures to avoid detection by law enforcement. This would not only potentially endanger the lives and physical safety of law enforcement of?cers and other individuals, but also adversely impact criminal investigations. Additionally, the information contained within the requested documents could be used to construct a map or directory of jurisdictions that possess the investigative capabilities, thereby providing further information for potential suspects that could be used to evade detection. Through public disclosures, the use of this technology will be rendered essentially useless for Future investigations. In order to ensure that such and any information related to its ?mctions, operation and use, is protected from potential compromise it is not subject to disclosure as a public record. For these reasons, the Department is denying your public records request. Please be advised that this of?ce does not provide legal assistance, opinions or explanations about police policy to the public, and will not respond to any such request. If you have been denied records by the Boston Police Department, you have the right to appeal this decision with the Supervisor of Public Records at the Public Records Division of the Secretary of the Commonwealth.
