constable on record was Joshua Pratt, in the Plymouth Colony. Constables were tasked with surveying land, serving warrants, and enforcing punishments. A rattlewatch was formed in New Amsterdam, later to become New York City, in 1651. The New York rattlewatch "strolled the streets to discourage crime and search for lawbreakers" and also served as town criers. In 1658, they began drawing pay, making them the first municipally funded police organization. When the English captured New Amsterdam in 1664, they installed a constable whose duties included keeping the peace, suppressing excessive drinking, gambling, prostitution, and preventing disturbances during church services. A night watch was formed in Philadelphia in 1700. In the Southern colonies, formal slave patrols were created as early as 1704 in the Carolinas in order to prevent slave rebellions and enslaved people from escaping. By 1785 the Charleston Guard and Watch had "a distinct chain of command, uniforms, sole responsibility for policing, salary, authorized use of force, and a focus on preventing 'crime'." Development of modern policing Modern policing began to emerge in the U.S. in the mid-nineteenth century, influenced by the British model of policing established in 1829 based on the Peelian principles. The first organized, publicly-funded professional full-time police services were established in Boston in 1838, New York in 1844, and Philadelphia in 1854. Slave patrols in the south were abolished upon the abolition of slavery in the 1860s. The legal tactics of the slave patrols are reflected in the vigilante tactics of the Ku Klux Klan. In the late 19th and early 20th century, there were few specialized units in police departments. In 1905, the Pennsylvania State Police became the first state police agency established in the United States, as recommended by President Theodore Roosevelt's Anthracite Strike Commission and Governor Samuel Pennypacker. The advent of the police car, two-way radio, and telephone in the early 20th century transformed policing into a reactive strategy that focused on responding to calls for service. In the 1920s, led by Berkeley, California police chief August Vollmer, police began to professionalize, adopt new technologies, and place emphasis on training. With this transformation, police command and control became more centralized. Orlando Winfield Wilson, a student of Vollmer, helped reduce corruption and introduce professionalism in Wichita, Kansas, and later in the Chicago Police Department. Strategies employed by O.W. Wilson included rotating officers from community to community to reduce their vulnerability to corruption, establishing
