A police badge is an official emblem worn by law enforcement officers to signify their authority and role in maintaining public safety. Typically made of metal, badges often feature a unique design that includes the name of the police department, the officer's rank, and sometimes a badge number. They serve as a symbol of trust and responsibility in the community. Badges are usually displayed on the officer's uniform, making it easy for the public to identify them. In addition to their practical use, police badges can also hold sentimental value for officers, representing their commitment to serve and protect the community they work in.
