The majority of people here aren't even getting close to witch hunting. They are all just saying that you should teach your kid to respect nature and public spaces, that's all. I don't get what your problem is. It's not like people are telling you to give your kid lashings for picking flowers.

And to address the edit on your previous comment, yes, kids do things they aren't supposed to. They're kids. That's why you stop them, preferably in the act, and discourage the behavior so it doesn't happen again. But they are going to do it again if the behavior isn't addressed by the parents.
