White and red are justice and blood. The starry field is nestled in blue - the states in law. The flag itself declares that law insulates the states from bloody-justice wars (from the SJW dream). The "thin blue line" co-opts the image to say that it keeps the states from sinking into such a quagmire (below the line); not by eliminating such violence (to the right of the field), but by minimizing it.

It's all well-done symbollism.
