The basic message of the “thin blue line” is that cops will cover for each other when they break the law.

This is seditious because they are essentially writing their own law and establishing sovereignty distinct, separate, and in conflict with the very lawful authority that pays their salaries and confers upon them their enforcement powers.

I always thought it meant a “thin blue line” between the bad guys and the citizens.

I’m sure that is the PC definition. Here is the one from Wikipedia:

The Thin Blue Line is a symbol used by law enforcement, originating in the United Kingdom but now prevalent in the United States and Canada to commemorate fallen and to show support for the living law enforcement officers and to symbolize the relationship of law enforcement in the community as the protectors of fellow civilians from criminal elements. It is an analogy to the term Thin Red Line.

Each stripe on the emblem represents certain respective figures: the blue centre line represents law enforcement, the top black stripe represents the public whilst the bottom represents the criminals. The idea behind the graphic is that law enforcement (the blue line) is what stands between the violence and victimization by criminals of the would-be victims of crime.[1]

Proponents of the symbol assert that the identifier is intended to show support for police.[1] In the wake of controversies over police shootings, the Thin Blue Line Flag has become popular among law enforcement personnel, their families and supporters.

Is this your own straw man?

If not, that is according to whom?

That has never been my understanding.

All my life, among normal people, it defined or represents the thin line between order or safety and chaos.
Easily broken by determined thugs.
