How did this common-sense-defeating liability culture actually start in the US? From a European perspective it is really strange to be liable in situations like this.
I find most of the CYA/liability things around childcare in modern west to be stupid (or amusing), but having nearly drowned in an abandoned pool as a young teenager, after wandering into it alone and getting stuck underwater for a moment throughout my own stupidity, I very much appreciate the idea described here, and think it's good.
