It sets a tone. People feel very twitchy now about where to take photos. It is part of the larger ethos that has been created, especially for men, where they are made to feel sheepish if they wish to get involved with either their children or working with other children.
I dont know if its a specific law. But I would like to see a repeal of the law that prohibits me from taking photos/videos of my children in school plays musicals and the like. It feels as if my children's childhood memories are being stolen by over zealous officials.
