The Kentucky State Police (KSP) is a department of the Kentucky Justice and Public Safety Cabinet. The department was founded in 1948 and replaced the Kentucky Highway Patrol. The department's officers are called troopers and its nickname is The Thin Gray Line.
In addition, the KSP operates the state's system of regional crime labs and is responsible for protecting the Governor, Lieutenant Governor, members of the Kentucky General Assembly and state property, including the Kentucky State Capitol Complex. On July 14, 2008, the Kentucky Vehicle Enforcement department, which is responsible for commercial vehicle enforcement, became a division of the KSP. The department's headquarters and training academy are located in Frankfort. The department also operates Trooper Island Camp, a juvenile crime prevention program at Dale Hollow Lake State Park.
