The Thin Blue Line represents Police Officers as they stand between law and order on one side and lawlessness on the other. Although not all Police Officers wear blue uniforms the majority of departments around the USA do, and as they are greatly outnumbered they refer to themselves as a ‘thin blue line’. Whenever an Officer is shot or killed in the line of duty you will see the Thin Blue Line representation to honor the “Fallen Officer”. My son is K9 Officer and he proudly flies the flag in his yard so neighbors or others driving by will know his house is a safe haven for someone in need.
The Thin Red Line represents the Fire Department and other First Responders such as EMT’s.
