Makes you wonder . . . But,
symbol Anon spotted is not exact match to BLogo that Anon provided.
BLogo from the center wraps Clockwise.
Civano symbol wraps counter-clockwise.
BLogo has six straight edges at 60° corners.
Civano symbol has only two straight edges and the rest is even more circular than the LBLogo.
Do you have more FBI documented symbols ?
There, you can make

NOTABLE .
