B) were relatively immune from politics and corruption

Before the twentieth century, police forces in the US had little to no legal or ethical controls, which often led to corruption and abuse of power. They were also underfunded and lacked proper training and equipment. It wasn't until the Progressive Era in the early 1900s that significant efforts were made to professionalize and reform policing. Therefore, options A, B, and D are not accurate representations of policing in the US prior to the twentieth century.
