And how that would undo the harm their stupid act did? My thinking is that the consequences of getting caught should not be limited to being punished, it should include a requirement that the perpetrator must undo the damage they did. If they spend the next 52 Saturdays removing garbage from beaches or parks for 8 hours, they will feel punished and they will have undid, at least some of the damage they did. If the right people are assigned to supervise them, maybe they can instill in them, a respect for the environment they obviously don't have now. If all you do is publicly flog them, all you will do is turn them into angry young men, no lesson learned.
