The Thin Blue Line is the philosophical construct of a line representing the separation of the law-abiding citizenry from lawlessness and criminality. On one side of the blue line are the lawless, corrupt, and criminal elements bent on the destruction of society. On the other side of the line is the innocent and law-abiding community members continually prayed upon.
Standing on the blue line and protecting the fabric of society are our law enforcement officers. Historically, the term Thin Blue Line was derived from The Thin Red Line, a military engagement during the Crimean War in 1854 by the British Sutherland Highlanders 93rd Regiment at the Battle of Balaklava. During the battle, the outnumbered men of the 93rd defeated a Russian cavalry charge. Typically firing from a four-man deep skirmish line on this day, they formed up two men deep, thus presenting a "thin red line" of riflemen. Firing three volleys, they caused the Russian retreat.
In 1911, N.D. Anderson's poem "The Thin Blue Line" likened the U.S. Army's blue uniforms' actions to the British actions in 1854.
The thin, blue line that fights for right,
That never bends the knee to might,
Has ever since it knew God's light
Fought dar Oppression in his lair,
And routed Wrong from valleys fair,
Sweet Peace and Plenty leaving there.
N.D. Anderson (1911): Partial excerpt
New York Police Commissioner Richard Enright is mostly attributed to applying the term to law enforcement and used the phrase in several speeches in the 1920s.
The Thin Blue Line phrase was further popularized by LAPD Chief William H. Parker, who used it as the title for the LAPD produced television program in 1952. He used it in numerous speeches referring to law enforcement as the "barrier between law and order and social and civil anarchy."
Only recently has the term come under attack by numerous groups as being divisive, oppressive, and racist. Not knowing the history of the phrase nor caring, these groups advocate disuse and removal of any referencing symbols. For several decades the representation of a black background separated by a blue line has symbolized The Thin Blue Line. My own agency's SWAT logo for over 40 years has been a black shield with a diagonal blue line.
Popular today is The Thin Blue Line Flag, a black-and-white American flag with the eighth state stripe depicted in blue. It represents solidarity among all law enforcement personnel and all those supporting their efforts regardless of race or political affiliation. Furthermore, it symbolizes their oath of office and adherence to the Law Enforcement Code of Ethics.
Anti-police factions recently politicized the slogan and the flag by inferring they represent a "Code of Silence," an oppressive history of police racism and civil rights abuses, and point to use by white supremacist groups. Further complicating the controversy is a reference to the Blue Lives Matter movement. This movement, advocating enhancements for criminals targeting law enforcement officers, is an entirely different discussion and postdates use of the flag.
Law enforcement leaders who fail to educate themselves or their politicians and communities on the Thin Blue Line's honorable history are likely to buckle under pressure for its eradication. Unwittingly they are undoing a proud history, alienating their ranks, and apologizing when none is warranted.
