You were brave! Not a very safe pitch to flash a camera. Especially if they think you are from the DSS!
Do you know what those stars mean? From Wiki (with reference to nautical stars) - When two stars are worn on the chest, the wearers left will be red, and the wearers right will be green. This represents port and starboard. At sea, if a vessel can view both port and starboard lights, it is an indication that another vessel is headed directly for them and they must "give way." In this sense, the port and starboard tattoo is a warning to others to "give way." Like other traditional sailor tattoos, this design should only be worn by those who have earned the right by: engaging in dangerous activities at sea, winning a bar fight in a foreign port, or other epic actions.
