Law Enforcement Accreditation

The Commission on Accreditation for Law Enforcement Agencies (CALEA), was formed in 1979 to establish a body of standards designed to:
  • Increase Law enforcement agency capabilities to prevent and control crime.
  • Increase agency effectiveness and efficiency in the delivery of law enforcement services.
  • Increase cooperation and coordination with other law enforcement agencies and with other agencies of the criminal justice system.
  • Increase citizen and employee confidence in the goals, objectives, policies, and practices of the agency.
In addition, the Commission was formed to develop an accreditation process that provides law enforcement agencies an opportunity to demonstrate voluntarily that they meet an established set of professional standards. The Commission began accrediting police agencies in 1986.

The Lake Zurich Police Department was first accredited in 2003.  The Department was reaccredited by the Commission in 2006, 2009, 2012, 2015 and 2019 demonstrating continued compliance with the Standards.

CALEA Reports and Analysis

Vehicle Pursuits

The pursuit of a suspect fleeing in a motor vehicle presents a danger to the safety of the pursuing peace officers, the suspect, other motorists, and bystanders in the vicinity of the pursuit. The decision to initiate or continue a pursuit requires the discretion of the involved peace officers while weighing numerous factors under varying conditions. 

During 2019, officers were involved in five incidents requiring the completion of the Pursuit Situation After-Action Report. Four incidents were within established policy parameters. One incident was not within established policy parameters. The involved officer received refresher training on the topic.  

Analysis of Grievances

The Lake Zurich Police Department maintains a grievance procedure designed to resolve matters between employees and the employer fairly and expeditiously. A grievance is any complaint concerning working conditions, classification, salary, or other work-related matters.  

An annual analysis of grievances is required to determine if a trend is observed and what steps may be taken to minimize the causes of such grievances in the future. There were no grievances filed on behalf of Lake Zurich Police Department employees during 2019 and only one in the previous six years.

Bias Based Policing

Since January 2004, police agencies in Illinois have been required to submit data about traffic stops to the Illinois Department of Transportation. Illinois Department of Transportation Division of Traffic Safety indicates Lake Zurich’s estimated minority driving population is 30%. Department data has never shown minority-stop data higher than 23%. In addition to traffic stops, Department policy requires an annual review of any discriminatory enforcement complaints. There were no such complaints during 2019.

Internal Investigations

The Lake Zurich Police Department follows an internal affairs policy to ensure prompt and thorough investigation of alleged transgressions and, if needed, take appropriate disciplinary action.

During 2019, there were two incidents which required internal investigations. These incidents were initiated by either an external or internal complaint.

Use-of-Force Analysis

Members of the Lake Zurich Police Department strive to accomplish the mission of the agency as efficiently as possible with the highest regard for the human dignity of all persons and with minimal reliance upon the use of physical force. The use of physical or deadly force should be restricted to circumstances authorized by law and only to accomplish lawful objectives. All sworn members of the Department are required to review the use-of-force policy annually. The policy is also reviewed during various training sessions throughout the year.

The Lake Zurich Police Department reviewed seven use-of-force incidents in 2019. All use-of-force incidents were determined to be within the guidelines of Department policy and procedure. Analysis of the 2019 use-of-force incidents revealed no specific training needs. No patterns or trends were noted indicating the need for equipment upgrades.
