"The first publicly funded, organized police force with officers on duty full-time was created in Boston in 1838. Boston was a large shipping commercial center, and businesses had been hiring people to protect their property and safeguard the transport of goods from the port of Boston to other places, says Potter. These merchants came up with a way to save money by transferring to the cost of maintaining a police force to citizens by arguing that it was for the “collective good.”

'At the same time, the late 19th century was the era of political machines, so police captains and sergeants for each precinct were often picked by the local political party ward leader, who often owned taverns or ran street gangs that intimidated voters. They then were able to use police to harass opponents of that particular political party, or provide payoffs for officers to turn a blind eye to allow illegal drinking, gambling and prostitution."
