Can anyone ID this flag?

I looked on Flags Of The World, googled, etc., but I can’t seem to figure this out…

I recently bought a used car that had this sticker on the bumper. Since then, I’ve seen quite a few of them, but I can’t figure out what they are. I don’t have a pic, so I’ll try to show you what I mean (the x’s represent solid color):
XXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXX

Any clues? Thanks!

That’s a “Thin Blue Line” sticker. It identifies the owner of the vehicle as a police officer (or a friend of the police). Some people get them as supposedly the cops are less likely to pull over a vehicle showing such a sticker.

Ah, that’s the one…

Thanks, tanstaafl!

I always thought those stickers were advertising some band I am not familiar with. Another mystery solved.

Are you sure it wasn’t a “Leather Daddy” symbol?

Was it this or this?

Is it like any of these?

The one you mention is used for mourning purposes.

The first one in your first link, yes.
