I had a thought while walking my parent's dog.
Cities with issues regarding defecation in public spaces would clean right up if public pooping were regarded as assault and citizens were encouraged to pepper-spray the perp's nether regions.
Cities throw up their hands in resignation because it is too expensive to process the countless perps. Pepper-spray is cheap. Pepper-spray is immediate. Peppet-spray is memorable...a significan't emotional event. And even the most emotionally distressed can process the message.
