Actually, the guy stated that this problem is so common in the area and interferes with his legitimate activity (birdwatching) that he carries the treats to deal with the problem, not that he’s simply going out to troll dog owners.
Again, what the guy did was fine. The issue I have is ruining someone’s life because of a short video of two people having a private verbal altercation. Do you believe she should have lost her job because of this?
