The story all began about six years ago in Miami-Dade County (the county just South of Broward), where the school district was struggling to succeed. All of the data painted a picture of a failing school district. The district noticed that large portions of their school populations were being arrested at a higher proportion than the rest of their community, and they realized that if they could cut down on the criminality of their students, they could quickly improve the data coming out of their schools.
With this in mind, the district entered into a relationship with their local police force and concluded a deal that would ensure the police would stop arresting so many of their students.
