What did the Chicago Police Department update in 1870?

The Chicago Police Department updated call booths in 1870 to enhance communication and reporting capabilities. The implementation of call booths represented a significant advancement in how police were able to receive information from the public. These booths allowed citizens to report crimes and emergencies directly to law enforcement, facilitating faster response times and improved coordination in public safety efforts.

The development of call booths played a crucial role in the evolution of policing and communication systems within urban areas. This innovation marked a shift from reliance solely on patrol officers for communication, making it simpler for citizens to communicate urgent issues or emergencies without needing to wait for an officer to be present.

In contrast, while call boxes and other communication devices were also prevalent during that time, the specific update in question highlights the move towards more direct and user-friendly means for civilians to engage with the police, which was embodied in the concept of call booths.
