A yard flag featuring a single horizontal blue line centered on a black and white American flag is a visual representation expressing support for law enforcement. The design typically involves a standard United States flag, altered to display thin blue line, often positioned between fields of black. These flags are designed for outdoor display, meant to be mounted on a flagpole and placed in a yard or garden.
The display of such flags reflects solidarity with police officers and honors those who have fallen in the line of duty. The symbolic blue line represents the barrier that law enforcement provides between order and chaos. Its presence in a residential setting can be interpreted as a declaration of support for the safety and security that these individuals provide to communities. Historically, the symbol has been used to demonstrate respect for those serving and protecting society, and to remember their sacrifices.
