Once a complaint has been filed with Internal Affairs, it is reviewed and assigned a classification based on the nature of the allegation. The most serious allegations, such as those involving criminal misconduct, excessive force resulting in injury requiring professional medical attention, and serious violations of policy, rules and regulations, are categorized as Class A Complaints. Class B Complaints are generally less serious violations of Department policy, rules and regulations. These may include improper language, inadequate service, excessive force without injury requiring treatment, and negligent damage or loss of property. Other complaints are classified as Administrative Complaints. Anyone making a complaint will receive a reply letter with notification of the outcome of the investigation.
