Why do we call them coppers?

Ladytrucker679:
My twelve year old son has just asked me why we call policemen, coppers. Now he is too young for me to tell him what I really call them but the only polite thing that I could come up with is;- :blush:

Constable
Of
Police.

Does anyone know?

When you get caught doing something you shouldn’t you get “copped”; that’s where it comes from. Don’t ask me about Plod, Fuzz or Pigs though… :confused:
