I've had my kid brought home by the cops twice. Both times he was playing on the sidewalk less than 50 feet from our front door. What do you even say to a cop that thinks allowing your child to play in their own front yard unsupervised is dangerous? It's insane. You risk getting a visit from CPS if your child goes unsupervised at any point in time. In practice, it's rare, but not so rare that parent's like me and my wife don't worry about every time our kids run outside to play.
