Police in Naperville say a woman who stepped in dog feces outside her apartment appears to have retaliated by heaving it at the door of her neighbor who owns a dog.
Susan Miller was charged with disorderly conduct after her bizarre protest Wednesday.
The Naperville Sun reports that police say Miller also uprooted a sign telling residents to pick up dog waste and placed it on the neighbor's patio. Miller was arrested after the neighbor called police.
An unapologetic Miller says if she can pick up the poop from her 80-pound dog, her neighbor can pick up after a 20-pound dog.
Naperville is about 30 miles west of Chicago.
