Kids should not be supervised at all times, but parents should also assume the risk for what happens when they aren't supervising their kids.
Managing risk-reward is a natural part of life and being an adult.
Attempts to completely eliminate risk leads to miserable lives and societies.
Covid response in certain jurisdictions was a great example of this. "If it saves even one more life, it's worth it!"
Hell no. A world where a nine or ten year old can’t go roam the neighborhood on bikes with some friends unless adults accompany them would be a dystopia. I know there are occasionally news stories about very-stupid harassment of parents for parenting correctly, but thank god it’s still not the norm.
No. The age which supervision is required varies by jurisdiction.
> And 14+ years old that drowns in a pool for inability to swim is also something that should be blamable on the parents, not the pool owner.
There's no law stating you need to teach your kids to swim.
Not in most jurisdictions (thanks God). That's a terrible idea for raising kids.
Civil suits are between citizens. Criminal suits generally have the plaintiff as the state government, albeit with rare exceptions such as RICO.
Edit with clarifications after comments: I meant, parent's should be supervising their young kids, or take the risk/blame, if something happens to the kids while they aren't.
(I roamed 'unsupervised' in fields and forest at young age with friends, and enjoyed it. But I was also taught to look where I step, and how to swim)
