I have just researched this as part of my PhD - Police work as entertainment. I concluded that there are 2 widely recognised symbols of policing:

1. The Sillitoe Tartan (checkered band)
2. The blue light. (Even though many police organisations now use a combination of red and blue the the blue revolving light is symbolic with police).
