During which era did American policing experience a major reform period?

The era from 1900 to 1940 is recognized as a significant reform period in American policing, often referred to as the Progressive Era. This period was characterized by a push for modernization and professionalization within police departments. Reformers aimed to reduce corruption and improve the effectiveness of law enforcement agencies.

Key developments included the establishment of police academies for training officers, the adoption of more scientific methods in investigations, and reforms aimed at increasing accountability and community relations. The influence of social sciences on policing also grew during this time, leading to a greater emphasis on data and statistics in crime analysis and prevention strategies.

These reforms were driven by community demands for more efficient policing and a desire to eliminate nepotism and bribery that were prevalent in many departments at the time. The Progressive movement highlighted the need for police to operate more independently from political influences, a shift intended to enhance public trust in law enforcement.

Understanding this context helps clarify why this era is considered pivotal for American policing. The changes initiated then laid the foundation for the expectations and practices of modern policing, distinguishing it from subsequent reforms that focused on different challenges and issues in law enforcement.
