The CFS **data** also captured proactive activities conducted by three distinct types of police units: patrol, specialized crime investigation, and the DRTs. Other than responding to calls, patrol officers also perform patrol duties, investigate suspicious activities, and form relationships with community members. Officers in specialized crime investigation divisions, such as robbery, vice, auto theft, gang, major assaults and family violence, and homicide divisions etc., mainly conduct investigations concerning specific type of offenses. Officers in DRT units do not respond to calls for service, instead, they proactively work with the community, focusing on problem solving and improving quality of life issues. These activities are all recorded as self-initiated activities within the CAD system.
