Do American police officers rely on connections for promotion?

American police officers do not rely on connections for promotion.

According to the recruitment and promotion system of the US police department, police promotion is mainly based on individual ability, performance and qualifications. Promotions typically require an assessment of an officer's professional knowledge, skills, and leadership abilities through a process of examinations, evaluations, and training. Relationships are not the determining factor for promotion, but individual ability and performance are the most important considerations.
