Sanilac County, MI--a large, highly rural county--is patrolled by 15 officers in 20 cars. Each car is equipped with a rugged laptop for mobile computing, which provides officers wireless access to Michigan's law enforcement information network, a comprehensive data repository. Officers are also using their laptops to write their own reports. Kent County, MI, which contains 22 townships and several incorporated cities, has a fleet of 50 cars equipped with rugged laptops. Blackberrys are hand-carried by detectives in the field, giving them access to a comprehensive database while conducting in-field investigations. These new wireless systems link officers to multiple databases and records management systems. In St. Joseph County, MI, mobile access to information and data involves patrol-car laptops and a global positioning system (GPS) that allows dispatchers to see the locations of patrol cars throughout the county. Mobile technology is moving into new applications that will further facilitate in-field law enforcement operations. These include rugged laptops with digital pens, GPS/mapping for airborne operations, voice response instead of keying on a laptop while in a vehicle, and a handheld device that instantly accesses information about a violator that would normally require a handwritten citation. This is launched by one query on a person or vehicle license. The citation is completed with the data received from the query. The future of mobile technology promises increased ease of use; add-on applications; system reliability, security, and compliance; and cost control.
