Cops and Robbers was a game I used to play in the street as a child, similar to "tag", but with distinct teams and more rules. Usually the Robbers would take an object and the objective would be for the Cops to get all all of the objects "back" to a certain point, but I think these were personal custom rules to the game.
My entry is a kitten pretending to be a Robber, fully kitted out with a costume (which we didnt have the luxury of having) and her "stolen" goods!
