As America entered the 20th century, the need for police reform and improvement was driven by several factors:

1. The need to establish police officer labor unions for the officers and administrators: This was important to ensure the rights and interests of police officers and administrators were protected. Labor unions would provide a platform for collective bargaining on issues such as wages, working conditions, and benefits.

2. Control over the police needed to come from the public: This was a call for greater accountability and transparency in the police force. The public, being the primary stakeholders in matters of security, needed to have a say in how the police force was run.

3. Police agencies to be more effectively organized: There was a need for better organization within police agencies to improve efficiency and effectiveness. This could involve restructuring, better resource allocation, and improved coordination among different units.

4. The need for more technology to be developed: The 20th century saw significant advancements in technology. There was a need for the police force to keep up with these advancements to improve their capabilities in crime prevention and detection. This could involve the use of new communication technologies, forensic tools, and surveillance systems.
