The badge that officers of Federal, State, City, County, and just about any other government that could issue a badge, would. I have been collecting badges for along time, and it never surprises me as to what there were on a badge. Here are just a few that I have seen.
Some outlaws said "the badge was just a target to shoot at". It's true; anything that was shiny was not good, because when you were tracking someone, anything that shined a reflection of the sun and let them know you were back there could get you killed.
