Interpreted slightly differently depending on who you ask, 1* can be thought of as those in the line of work, usually a dangerous line of work, that involves protecting the people or the public. Knowing the meaning of 1* POLICE is a frame of mind. This is why 1* POLICE is so appropriate for this engraved port cover. Go forward, and protect.
