Here's an example. This guy walks his dog every day and lets it do it's business in everybody's yard along the way. Here is the dog in the yard of a neighbor who is having some construction work done. This is about the 4th yard the dog desecrated along the way. I said to the guy, "why not use your own yard?" He just gave me a bad look and kept walking. You'll notice that he has no bag in his hand. That little white thing is a ball or something else, but not a plastic bag. The next time, I'll get a close up of his face.
