Based on reading the following passage, which of the following best explain why the Pinkerton National Detective Agency’s main customers were railroad companies? Check all that apply. The early private security industry dates back to 1850 when Allan Pinkerton founded the Chicago-based Pinkerton National Detective Agency. It became the largest private security agency in the country. Its main customers were railroad companies. The Pinkerton agency worked to chase outlaws, who robbed trains of cargo and took personal possessions from passengers, across territorial and state lines. At that time, there was no federal agency to chase outlaws. There also was no local law enforcement to pursue perpetrators of crime locally or across state or territorial lines.

Over time, federal and local agencies improved law enforcement capabilities, particularly after 1900.

A. Train robbers would cross state lines, and there was no federal agency to chase outlaws.
B. Railroad companies were the most successful businesses at the time, so they were able to afford the fees charged by the Pinkerton agency.
C. Train robbers would cross state lines, and there was no local law enforcement to pursue perpetrators of crime locally or across state or territorial lines.
D. The Pinkerton agency preferred to only work with the railroad industry.
