Note the proximity to the garbage can.

Most dog owners are fairly conscientious about their animal’s droppings. There is however one idiot who makes a practice of leaving the full bag of crap along the pathways frequented mainly by other dog owners. I have no idea what the motivation is for preserving the excrement in plastic other than bone idleness and lack of consideration. The result of this dimwit’s anti-social behaviour is a series of excrement-filled bags scattered throughout the park. In some places, there is even a pile of the bags; perhaps a favourite spot to desecrate although it’s possibly secluded enough for them to drop the bag with impunity. This idiot gives all dog owners a bad name.

The bags are distinctive; small and white with two handles that form loops.
