What represents about 270,000 of the 600,000 active police officers in the United States?

The Fraternal Order of Police is the largest organization representing law enforcement officers in the United States, with approximately 270,000 members out of the total 600,000 active police officers. This organization is dedicated to advocating for the interests of police officers, including efforts to enhance working conditions, provide resources, and promote benefits for members. Its significant membership reflects its role as an influential voice in the law enforcement community, providing support and advocacy for officers across various jurisdictions.

The National Police Association, while active in promoting the interests of law enforcement, does not have as large a membership base. The Federal Bureau of Investigation, as a federal agency, serves distinct functions related to national security and federal law enforcement, and it's not primarily a representative body for active police officers in the same way as the Fraternal Order of Police. The United Police Federation represents specific groups of officers but does not encompass the broader membership that the Fraternal Order of Police does. Thus, the correct answer highlights the Fraternal Order of Police's prominence and extensive member reach within the law enforcement community.
