 Reminiscent of the blue in their uniforms, the thin blue line emblem has multiple meanings, all around the same concept, Police officers standing as the thin line that protects society from good and evil, chaos and order. It is also considered an homage to those fallen in the line of duty as it represents the thin line between life and death that officers face everyday.
