Thin Blue Line Flag (United States) ラゲッジタグ

The "Thin Blue Line" is a concept that dates back to the 19th century, originally referring to the British infantry (the "Thin Red Line"), but it was adapted by American police departments in the mid-20th century. The blue line represents the police officer as the barrier between "order" and "anarchy." In a modern context, this symbol is a gesture of solidarity with the men and women of law enforcement. For those who display it on their luggage, it often signifies a personal connection to the profession—whether the traveler is an officer, a family member, or a supporter. The monochrome black and white design creates a somber tone, intended to honor those who have fallen in the line of duty, while the single blue stripe stands out as a tribute to the courage of those currently serving on the "front lines" of civil society.
